Can you make music from Joshua trees — or is that wild science? Yes.

Artist Scott Kildall waves his microcontroller over a Joshua tree, recording wavelengths of light that are not perceptible by humans.

The artist Scott Kildall is waving his hand over the contours of a Joshua tree, just inches from its spiky green, bayonet-like leaves.

“If I get too close to it, it will prick me and draw blood,” he says. “And it’s done that before.”

In his palm, he has a microcontroller — just about the size of a credit card. It’s got a few wires sticking out, and an infrared sensor, which picks up wavelengths of light just beyond what the human eye can perceive.

“It’s kind of like magic,” Kildall says. “And the magic is just revealing something that’s right beyond our levels of perception.”

The magic is part of Kildall’s latest sound installation — a work he calls Infrared Reflections. He developed the piece as an artist-in-residence at Joshua Tree National Park this spring, and it transforms near-infrared light bouncing off the iconic scraggly yuccas into a shimmering mosaic of otherworldly music — essentially turning the Joshua tree into an instrument.

Kildall is neither a computer scientist nor a musician, though he does play the ukulele. This artwork relies on both disciplines, as Kildall needs to build sensors, route their data to a computer, process and smooth that data, and convert it all into something beautiful for the ear.

“With art and technology, you have to constantly think about wearing multiple hats. Are you an IT person? Are you an artist? And you have to be able to troubleshoot on the fly,” he says.

The installation relies on a fundamental interplay between the sun and the Joshua tree. When sunlight hits the plant, cells in its healthy leaves soak up lots of red and blue light, and reflect back most of the green – which is why the clusters of piercing leaves at the end of the Joshua tree’s branches appear green to the human eye. (It’s also why most plants on Earth appear green to us.)

But other types of light rain down on the Joshua tree too, including wavelengths we can’t see, like near-infrared light. The plant’s shaggy, grayish-brown bark doesn’t reflect much of that infrared light, but its healthy leaves — packed with compounds like water, carbohydrates and defense chemicals — reflect much more. And that’s exactly what Kildall sees as he passes his sensor from the yucca’s dead bark to its green, leafy buds.

“Beyond our perceptions lies a whole realm of invisible data,” he explains. “And so what I do is I find some sort of invisible phenomena such as water quality or air quality or infrared light reflection, and then map that data into sounds, so that we can hear that data.”

That technique is known as sonification, and Kildall has previously designed installations that sonify water flow in trees, or tap into the electrical signals of mushrooms. Infrared Reflections follows in that vein, but it’s much more site-specific — it’s meant to be played on the Joshua tree, which is endemic to the Mojave Desert.

With that in mind, earlier today Kildall lugged his laptop, a box of electronics and a giant speaker into a field full of Joshua trees at the Arthur B. Ripley Desert Woodland State Park, north of Los Angeles.

Gusts of wind scream through the high desert here, and Kildall eyes individual Joshua trees with the eagerness of a kid at Guitar Center, ready to pick out an axe.

“I see one Joshua tree that’s about a hundred feet away that is moving a little bit in the wind and has multiple leafy sections and bark sections,” he says. “And that one really looks like it is asking to be sonified.”

After a short walk, Kildall sets down the speaker and begins fiddling with his laptop. It’s perched on a camp chair, in direct sun, and refuses to boot up — a reminder, Kildall says, of how preparing for a field installation is like planning a NASA space mission (though with non-lethal stakes.)

“You want to reduce the number of points of failure. And so with the system I have, I have backup electronics, I only have one laptop. So that’s the only point of failure that I’m really worried about.”

But not to fear. The machine soon boots up, along with a local Wi-Fi network — which connects the small infrared sensor to the computer — and Kildall is ready to rock.

Here’s the same landscape viewed through a thermal infrared camera. It captures a different part of the infrared spectrum from what Kildall is picking up with his sensor, but gives a sense of how these plants appear differently when viewed at different wavelengths of light.

As he caresses the air just above the tree, the yowling of a theremin rises and falls from the speaker, lending an eerie soundtrack to the already alien-looking landscape. A few hikers walk by, but seem unphased by the guy performing reiki on a Joshua tree. The high desert is known for its eccentrics, after all.

Kildall has designed three more “instruments” to be played like this, along with the theremin sound.

His favorite combines the drone of a theremin with spiraling arpeggios.

Another sounds more like haunting electric guitars, reverberating in a cathedral.

The final sound is more pared-back and simple — resembling a kid plinking at the piano.

“In some ways, it feels a little bit more direct and accessible because we all kind of understand how to press notes randomly on the piano,” Kildall explains. “And as I move the sensor over these sort of leafy spots in the sun, those will produce a higher pitch on the piano.”

As he slides the sensor further down the branch, to the bark, the notes get lower and lower, moving deeper into the bass clef.

It’s a fascinating way to make music. The infrared-sensing technology at the heart of the work also happens to be something scientists have employed for decades.

“From our aircraft or satellites, we use it to separate the living vegetation from the dead vegetation,” says Greg Asner of Arizona State University in Hawaii. “That’s very important in a grassland — is the grassland dry and ready to go up in smoke in a fire, or is it wet and green and living? And so we can translate that to fire fuel load for grasslands.”

Asner has also soared above the Amazon basin, measuring infrared signals from a plane — which allows him to tease out individual tree species, based on the fingerprints of infrared light that bounce off the trees.

“When I fly over a tropical rainforest with the infrared sensors, the maps literally are like Willy-Wonka-candy-store-style variation. They are amazing to look at,” he says.

“So there’s this enormous diversity of plants when you look at them in infrared light. And unfortunately, a lot of people just see them as green because that’s all we can see with our limited eyesight. There’s much more variety out there. And it’s a very beautiful world when you look at it in the infrared.”

Asner says he’s thrilled to see artists now experimenting with the same technology.

“Our studies for decades now have been stuck in the halls of science. And this will help translate what we have come to understand, utilize, love as scientists — it’s going to translate it to a much wider audience.”

Kildall says, in some sense, that’s his goal.

“One of the things I like to do is to engage people with nature and issues of climate change and issues of ecology through means other than science articles,” he says. “Science articles are great. I read them all the time. However, they don’t engage people on a more visceral storytelling level, as artwork does.”

And though this installation was conceived and developed with the Joshua tree at its center, it could work with the infrared reflections of other plants, if Kildall calibrates his code — which is a good thing, since Kildall calls San Francisco home.

“There aren’t any Joshua trees in San Francisco, so I might have to go to Golden Gate Park and see what I come up with.”

‘American Classic’ is a hidden gem that gets even better as it goes

American Classic is a hidden gem, in more ways than one. It’s hidden because it’s on MGM+, a stand-alone streaming service that, let’s face it, most people don’t have. But MGM+ is available without subscription for a seven-day free trial, on its website or through Prime Video and Roku. And you should find and watch American Classic, because it’s an absolutely charming and wonderful TV jewel.

Charming, in the way it brings small towns and ordinary people to life, as in Northern Exposure. Wonderful, in the way it reflects the joys of local theater productions, as in Slings & Arrows, and the American Playhouse production of Kurt Vonnegut’s Who Am I This Time?

The creators of American Classic are Michael Hoffman and Bob Martin. Martin co-wrote and co-created Slings & Arrows, so that comparison comes easily. And back in the early 1980s, Who Am I This Time? was about people who transformed onstage from ordinary citizens into extraordinary performers. It’s a conceit that works only if you have brilliant actors to bring it to life convincingly. That American Playhouse production had two young actors — Christopher Walken and Susan Sarandon — so yes, it worked. And American Classic, with its mix of veteran and young actors, does, too.

American Classic begins with Kevin Kline, as Shakespearean actor Richard Bean, confronting a New York Times drama critic about his negative opening-night review of Richard’s King Lear. The next day, Richard’s agent, played by Tony Shalhoub, calls Richard in to tell him his tantrum was captured by cellphone and went viral, and that he has to lay low for a while.

Richard returns home to the small town of Millersburg, Pa., where his parents ran a local theater. Almost everyone we meet is a treasure. His father, who has bouts of dementia, is played by Len Cariou, who starred on Broadway in Sweeney Todd. Richard’s brother, Jon, is played by Jon Tenney of The Closer, and his wife, Kristen, is played by the great Laura Linney, from Ozark and John Adams.

Things get even more complicated because the old theater is now a dinner theater, filling its schedule with performances by touring regional companies. Its survival is at risk, so Richard decides to save the theater by mounting a new production of Thornton Wilder’s Our Town, casting the local small-town residents to play … local small-town residents.

Miranda, Richard’s college-bound niece, continues the family theatrical tradition — and Nell Verlaque, the young actress who plays her, has a breakout role here. She’s terrific — funny, touching, totally natural. And when she takes the stage as Emily in Our Town, she’s heart-wrenching. Playwright Wilder is served magnificently here — and so is William Shakespeare, whose works and words Kline tackles in more than one inspirational scene in this series.

I don’t want to reveal too much about the conflicts, and surprises, in American Classic, but please trust me: The more episodes you watch, the better it gets. The characters evolve, and go in unexpected directions and pairings. Kline’s Richard starts out thinking about only himself, but ends up just the opposite. And if, as Shakespeare wrote, the play’s the thing, the thing here is, the plays we see, and the soliloquies we hear, are spellbinding.

And there’s plenty of fun to be had outside the classics in American Classic. The table reads are the most delightful since the ones in Only Murders in the Building. The dinner-table arguments are the most explosive since the ones in The Bear. Some scenes are take-your-breath-away dramatic. Others are infectiously silly, as when Richard works with a cast member forced upon him by the angel of this new Our Town production.

Take the effort to find, and watch, American Classic. It’ll remind you why, when it’s this good, it’s easy to love the theater. And television.

The L.A. coffee shop is for wearing Dries Van Noten head to toe

The L.A. coffee shop is for wearing Dries Van Noten head to toe

The ritual of meeting up and hanging out at a coffee shop in L.A. is a showcase of style filled with a subtle site-specific tension. Don’t you see it? Comfort battles formality fighting to break free. Hiding out chafes against being perceived. In the end, we make ourselves at home at all costs — and pull a look while doing it.

It’s the morning after a night out. Two friends meet up at Chainsaw in Melrose Hill, the cafe with the flan lattes, crispy arepas and sorbet-colored wall everybody and their mom has been talking about.

Miraculously, the line of people that usually snakes down Melrose yearning for a slice of chef Karla Subero Pittol’s passion lime fruit icebox pie is nonexistent today. Thank God, because the party was sick last night — the DJ mixed Nelly Furtado’s “Promiscuous” into Peaches’ “F— the Pain Away” and the walls were sweating — so making it to the cafe’s front door alone is like wading through viscous, knee-high water. Senses dull and blunt in that special way where it feels like your brain is wearing a weighted vest. The sun, an oppressor. Caffeine needed via IV drip.

The mood: “Don’t look at me,” as they look around furtively, still waking up. “But wait, do. I’m wearing the new Dries Van Noten from head to toe.”

If a fit is fire and no one is around to see it, does it make a sound? A certain kind of L.A. coffee shop is (blessedly) one of the few everyday runways we have, followed up by the Los Feliz post office and the Alvarado Car Wash in Echo Park. We come to a coffee shop like Chainsaw for strawberry matchas the color of emeralds and rubies and crackling papas fritas that come with a tamarind barbecue sauce so good it may as well be categorized as a Schedule 1. But we stay for something else.

There is a game we play at the L.A. coffee shop. We’re all in on it — the deniers especially. It can best be summed up by that mood: “Don’t look at me. But wait, do.” Do. Do. Do. Do. We go to a coffee shop to see each other, to be seen. And we pretend we’re not doing it. How cute. Yes, I’m peering at you from behind my hoodie and my sunglasses but the hoodie is a niche L.A. brand and the glasses are vintage designer. I wore them just for you. One time I was sitting at what is to me amazing and to some an insufferable coffee shop in the Arts District where a regular was wearing a headpiece made entirely of plastic sunglasses that covered every inch of his face — at least a foot long in all directions — jangling with every movement he made. Respect, I thought.

Dries Van Noten’s spring/summer 2026 collection feels so right in a place like this. The women’s show, titled “Wavelength,” is about “balancing hard and soft, stiff and fluid, casual and refined, simple and complex,” writes designer Julian Klausner in the show notes. While for the men’s show, titled “A Perfect Day,” Klausner contextualizes: “A man in love, on a stroll at the beach at dawn, after a party. Shirt unbuttoned, sleeves rolled up, the silhouette takes on a new life. I asked myself: What is formal? What is casual? How do these feel?” What is formal or casual? How do you balance hard and soft? The L.A. coffee shop is a container for this spectrum. A dynamic that works because of the tension. A master class in this beautiful dance. There is no more fitting place to wear the SS26 Dries beige tuxedo jacket with heather gray capri sweats and pink satin boxing boots, no better audience for the floor-length striped sheer gown worn with satin sneakers — because even though no one will bat an eye, you trust that your contribution has been clocked and appreciated.

Back at Chainsaw the friends drink their iced lattes, they eat their beautiful chocolate milk tres leches in a coupe. They’re revived — buzzing, even; at the glorious point in the caffeinated beverage where everything is beautiful, nothing hurts and at least one of them feels like a creative genius. The longer they stay, the more their style reveals itself. Before they were flexing in a secret way. Now they’re just flexing. Looking back at you looking at them, the contract understood. Doing it for the show. Wait, when did they change? How long have they been here? It doesn’t matter. They have all day. Time ceases to exist in a place like this.

In Disney and Pixar’s delightful new film Hoppers, a young woman (Piper Curda) learns a beloved glade is under threat from the town’s slimy mayor (Jon Hamm). But luckily, she discovers that her college professor has developed technology that can let her live as one of the critters she loves – by allowing her mind to “hop” into an animatronic beaver. And it just might just allow her to help save the glade from serious risk of destruction.
