Andromeda was a psychedelic-progressive rock trio formed by singer-guitarist John Cann (also known as John Du Cann), formerly of the psychedelic garage band the Attack, Mick Hawksworth (bass, vocals) and Ian McClane (drums, vocals). The group performed in various London venues including Middle Earth and the Marquee Club. Cann's guitar was the dominant instrument, leading listeners through classically- based psychedelic and progressive directions and creative dissonances, contributing to the trio's impressive live sets. Andromeda combined their own original writing with elements appropriated out of familiar classical material.
