42 years ago today (2/24/75), Led Zeppelin released their sixth studio album Physical Graffiti, one that many consider their finest. These eight songs stretched the total time of the record beyond the typical length of a single LP, so the band decided to make Physical Graffiti a double album 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 the unused title track. Physical Graffiti was commercially and critically successful; the album went 16x platinum in the US in 2006, signifying shipments of eight million copies, and was a number one album in both the US and UK. Watch Zeppelin perform the personal and reflective “Ten Years Gone” off Physical Graffiti live at Knebworth 1979.
