Alexander Lee "Skip" Spence was a Canadian-born American musician and singer-songwriter. He was co-founder of Moby Grape, and played guitar with them until 1969. He released one solo album, 1969's 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 addictions 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."
