The Ventures - Super Psychedelics (1967)
This is my favorite album by the criminally underrated instrumental psychedelic surf guitar group. Pioneers in using pedals and effects in their compositions and covers, the album is rich with guitar tones. Tremolo-picked fuzz guitar joins sitars, flangers, phasers, theremins, and all manners of cool guitar tones as The Ventures chew their way through the pop hits of the 60s.
Though their original compositions are fun, and have mostly aged well, my favorite songs on this record are primarily the covers. "Strawberry Fields Forever", "Happy Together", and "A Little Bit Me, A Little Bit You" are each at least as good as the originals, and tend to add a great deal to their source material.
