The Monks (Sixties US group, famed for early use of feedback)
The Monks were an avant-garde garage rock band, formed by American GIs who were based in Germany in the mid- to late 1960s. They released one album, Black Monk Time, which was characterized by repetitive, unconventional, and often primitive music and chanted lyrics.
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.
