Alexander Lee "Skip" Spence (April 18, 1946 – April 16, 1999) was a musician and singer-songwriter best known for his work with Jefferson Airplane, Moby Grape and as a solo artist. 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." During his tenure in the public eye, he had a profound impact on the outsider music and psych-folk genres.
