Relics is a compilation that originally appeared in 1971 and sums up Pink Floyd's early years. It gathers the singles from the Syd Barrett period — "Arnold Layne", "See Emily Play", "Paint Box" and "Julia Dream" — with album tracks such as "Interstellar Overdrive", "Remember a Day", "Cirrus Minor" and "The Nile Song", and closes with "Bike" from the debut album. New to the compilation was "Biding My Time", a previously unreleased Roger Waters song from 1969 with a trombone solo by Richard Wright. The original sleeve was a drawing of an imaginary machine by drummer Nick Mason. This edition is an LP.
