Bachdenkel were an English rock group which came to life in and around the King's Heath area of Birmingham in the late 1960s, evolving out of a combo called "U No Who". Their name was produced by computer - an innovative use of new technology in those days - and they were one of the seminal bands on the Birmingham scene during the late 1960s, which saw the development of psychedelic culture and electric rock music. They had close links with the Birmingham Arts Lab, a venue for experimental artists of all types, and often performed with a full psychedelic light show.
