Ray Barretto - Acid (1968)
Despite the title and the visuals on the cover, this is not an album of psychedelic music. It's an album of Latin soul/jazz from drummer, conga player and percussionist Ray Barretto. One song (Teacher of Love) is a bit weak, compared with the rest of the album, but other than that it's a solid effort. The song "Deeper Shade of Soul" was covered by the Dutch band "Urban Dance Squad" and became a 1991 Billboard Hot 100 #21 hit for that group.
