Moby Grape

Moby Grape is an American rock band founded in 1966. Part of San Francisco's psychedelic music scene, the band merged elements of rock and roll, folk music, pop, blues, and country. They were one of the few groups of which all members were lead vocalists and songwriters. The group's first incarnation ended in 1969, in part due to members Bob Mosley and Skip Spence suffering from mental illness. The group has reformed many times afterwards and continues to perform occasionally.
