Craig Colorusso is, in his own words, “just a rocker.” His arsenal includes a guitar and a bass clarinet; he’s toured the country with various bands, playing in various capacities.

But in Mr. Colorusso’s latest piece of work, which traveled to the Vineyard for a four-day run last week, there is neither band nor backup singers. The only soloist is the sun.

Much like a great concert would be, however, Sun Boxes is an experience.

As people descended onto Lambert’s Cove Beach last Sunday they didn’t know whether to walk around the 20 portable speakers or through them, or to just turn around, worried they were interrupting a private function. Mr. Colorusso asked onlookers to stay until it was time to turn the speakers around. And then one by one, Mr. Colorusso turned the boxes in their place, so the small solar panel mounted atop each faced the sky.

A light chime began to play one after another until the notes intertwined to create a steady whistle, settling in as if it had always been there with the ocean.

Mr. Colorusso encouraged the beachgoers to mingle inside the boxes to get their full effect. A few participants lay on the ground, closed their eyes and let the tones wash over them. The delicate hum of B-flat notes easily became a part of their breathing rhythm, seeming to touch on an internal chord of peace and meditation.

“I just fell in love with the B flat six,” Mr. Colorusso said of his note of choice. “It’s got the right amount of dissonance to just give you that thought-provoking avenue if you choose, but ultimately it’s very soothing.

“I like dissonant music. But I wanted this to be very calm and regenerative and make you feel good afterwards,” he continued.

“They’re so chill and mellow and decompressing,” said Diana Reilly of West Tisbury, who initiated the drive to bring Sun Boxes to Martha’s Vineyard after seeing Mr. Colorusso’s project at an event in western Massachusetts. “We were like, oh, these things should be on the beaches.”

In addition to the afternoon at Lambert’s Cove, the Sun Boxes made appearances at the Field Gallery and the Farm, Institute before wrapping up the visit at Menemsha Beach on Monday.

Mr. Colorusso’s time spent on tour informed the design and concept of Sun Boxes.

“I loved being on stage,” he explained, “But there’s that idea of the barrier between audience and performer, and I just wanted to make something that people could feel like they’re part of . . . with Sun Boxes, you can walk out in the middle of it and . . . I think that’s really cool, the physicality of it.”

Inside each homemade wooden speaker is a PC board with a power amp and a sampler on it; each sampler contains a single prerecorded guitar note and is programmed to play continuously so long as there’s enough sun.

“The catch,” said Mr. Colorusso, “is all the samples are different lengths, so as they’re repeating they’re lining up differently.

“According to my calculations it would take several months before the whole thing would repeat again.”

Rain cancelled Mr. Colorusso’s original plans for a 10-day stint on the Island, but he points out that inclement weather can bring out the best Sun Boxes has to offer.

“There’s no batteries, so when the clouds come it gets a little quiet — sometimes it stops altogether,” he said.

“But most times the sun burns through, and they all start up together, and it’s glorious.”
