The National Gallery of Art’s Dan Flavin exhibition may now be just a fluorescent imprint in the back of your brain, but fear not, fans of light art: Leo Villareal is back in town—and in force. Villareal, a New York– based artist who uses light-emitting diodes (LEDs) to craft dazzling, animated sculptures of light, has a solo exhibition at Conner Contemporary Art beginning June 18 and contributes work to the 40-artist Hirshhorn Museum and Sculpture Garden survey show “Visual Music,” which examines the multisensory intersection of abstraction, color, and music beginning June 23. Villareal says his techniques allow him to create more than 16 million colors, which means his work offers a mind-bending experience even if you don’t tote along Pink Floyd on your iPod. Your retinas may never be the same after Villareal discusses how and why he makes his art at 7:30 p.m. in the Hirshhorn Museum and Sculpture Garden’s Ring Auditorium, 7th Street and Independence Avenue SW.
