San Francisco original Alexander ‘Skip” Spence. Lived on Haight Street for years, then in San Jose and Santa Cruz where his family is today
aka The Prison Song, recorded by original Quicksilver Messenger Service, Jefferson Airplane and Moby Grape member Skip Spence shortly after release from a mental hospital after taking acid and going at the door of a fellow band mate with an axe
The Album is called OAR, recorded in Nashville in 1969 and Skip is the entire band, played all instruments
A tribute album called More Oar was recorded in 1999 by the likes of Tom Waits, Robert Plant and Beck
Oar, to this day, is considered one of the most enigmatic solo albums of all time, a true solo album where all the instruments, parts and vocals were done by one person
PS, if you read the Wiki page, there’s a mention that Skip recorded a song for the X-Files just before he died. What isn’t mentioned, and what most people don’t know is that Land of the Sun was rejected by the X-Files as ‘too strange’
