The Soundhouse Tapes is the debut EP by Iron Maiden, and features the very first recordings by the band. Released on 9 November 1979, it features three songs taken from the demo tape recorded at Spaceward Studios on New Year's Eve 1978. The three tracks - "Prowler", "Invasion" and "Iron Maiden" - appear in a rougher form than they would on the first Iron Maiden album and subsequent singles as they were all recorded in one session.
