If you’re in the mood for something a little unusual tonight, you’re in luck. In celebration of the opening weekend of their new visual music exhibit, the Hirshhorn museum will be open from 9:30 p.m. until 2 a.m. The exhibit explores “the many forms of visual music, an interdisciplinary, broad-based art movement that explored the relationship of abstraction, color, and music.” Their online exhibit has more photos and information about the paintings, film, and installation art on display.

In addition to getting a late-night peek at the exhibit tonight, Joshua White and Gary Panter will be producing a psychedelic light show they’re calling “Cosmic Drift.” We’re told that “Joshua White achieved acclaim in the 1960s for The Joshua Light Show, in which he created kaleidoscopic, mind-bending effects for the likes of Janis Joplin, Frank Zappa, Jimi Hendrix, and the Allman Brothers Band.” Groovy! The show will go on rain or shine, and alcohol is prohibited.
