The Enduring Legacy of Jerry Garcia

The Electric Kool-Aid Acid Test
The Dead gained its early audience by performing as the house band at the many LSD parties, known as "acid tests," that were organized widely in the Bay Area in the mid-1960s. The scene, centered on the intersection of Haight and Ashbury streets, was later memorialized in a best-selling work by Tom Wolfe, who stands with Garcia and Dead manager Rock Sculley in this 1966 photo.
