Singer, songwriter, and guitarist John Parker Compton co-founded the acoustic band APPALOOSA with violinist Robin Batteau in the late '60s. Both musicians had been heavily influenced by the folk scene in their hometown, Cambridge, MA.
As the 1972 press release for Compton's solo album, To Luna, tells it, John Compton showed up at producer Al Kooper's Columbia Records office in late 1968, hoping to show Kooper his songs. Uninterested, Kooper told the kid - Compton was 18 to come back some other time.
It would be over 20 years before he returned to the studios.
