Query: Heavy Mod Psych Madness

Crazed Mod Psychedelic masterpiece never released in the U.S. (probably judged too british by american label execs). Roy Wood was every bit as talented as Syd Barrett, Pete Townsend or Steve Marriot and deserves much wider acclaim. Balances insanely catchy melodies with heavy, almost proto-metallic riffage.
