Country Joe & The Fish - Electric Music For the Mind and Body (1967 Vanguard)

I like how they use organ and harmonica on "Section 43". The material is quite eclectic, maybe too eclectic for me. The best ones are "Section 43", "Bass Strings" and nice, psychedelic "Grace". Good album, but not that good.
