The Joshua Light Show, which illuminated many Grateful Dead concerts at New York’s Fillmore East, will enhance two dates on Warren Haynes’ upcoming Jerry Garcia Symphonic Celebration. Those shows include Haynes’ stop at Lenox, MA’s Tanglewood Music Center on June 22 and his performance at Philadelphia’s The Mann Center for the Performing Arts on June 25.

The Joshua Light Show took hold at the Fillmore East in the late 1960’s presenting psychedelic accompaniment to the music of the Dead, Allman Brothers Band, Frank Zappa, Janis Joplin and many others. More recently, after spending many years working in television, the Joshua Light Show’s Joshua White has shifted his focus back to musical performances, working with the likes of MGMT, Woods, Lou Reed and others.
