Digging around old music, I found a noteworthy album entilted Oar by former drummer for Jefferson Airplane and acid casualty Alexander "Skip" Spence. The solo album was released in 1969 and recorded six months after Spence's release from Bellevue Hospital. While the album consists mostly of incoherent ramblings and lyrical musings, the "turn on, tune in, drop out" sound is prevalent.
