In the key of see

MOST of the focus at the Coachella Valley Music & Arts Festival is on the sounds emanating from the desert. But as the word “art” indicates, there are plenty of visual atmospherics as well, on stage and off. Take the Los Angeles-based artist known as Pop Levi. He played his set of retro-glam power-pop sporting what he calls “The Wonder Shirt” -- and it’s a wonder it held up in the 105-degree heat. The shirt, he explains, was originally a knee-length dress he found in a L.A. store. The singer-guitarist, the former bass player in the English electro band Ladytron, took it with him to China, where he had a Shanghai tailor re-cut it into a shirt. How does he describe it? “Stained-glass shock,” he says.

Elsewhere, art high-volume and not: a field of Sunflower Robots blinking their solar-powered lights toward the crowd, customized turntables and bands, posterized.
