The Monks (not to be mistaken with the british punk-rock band from the 70's) are a garage rock band, primarily active in Germany in the mid to late sixties. They reunited in 1999 and have continued to play concerts, although no new studio recordings have been made. The Monks stood out from the music of the time, and have developed a cult following amongst many musicians and music fans. They style seems to be an advance of what later became punk-rock. A must!
Here you have two albums: Black Monk Time, and Demo Tapes. Both compilations of their songs.
