open today 12 to 7 ! on this date 40 years ago ! Physical Graffiti is the sixth studio alb** by the English rock band Led Zeppelin, released on 24 February 1975 as a double alb** two years after their previous studio alb**. The band wrote and recorded eight songs at Headley Grange; these eight songs stretched beyond the typical length of an LP. The band decided to make Physical Graffiti a double alb** by including unreleased tracks from earlier recording sessions: one outtake from Led Zeppelin III; three from Led Zeppelin IV; and three from Houses of the Holy including its unused t**le track.
