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.

Alexander "Skip" Spence was a Canadian-born American singer-songwriter and musician. He was co-founder of Moby Grape, and played guitar with them until 1969. In the same year, he released his only solo album, Oar, and then largely withdrew from the music industry. He had started his career as a guitarist in an early line-up of Quicksilver Messenger Service, and was the drummer on Jefferson Airplane's debut album, Jefferson Airplane Takes Off. He has been described on the AllMusic website as "one of psychedelia's brightest lights"; however, his career was plagued by drug addiction coupled with mental health problems, and he has been described by a biographer as a man who "neither died young nor had a chance to find his way out."
