Released on this day in 1975, Physical Graffiti is the sixth studio album from Led Zeppelin, and the first release on their own Swan Song label. The double album has been certified 16X platinum in the United States thanks to great songs like "Kashmir", "Trampled Under Foot", "Houses Of The Holy" and my all time fave Zep jam "Ten Years Gone" (above). A remastered version of Physical Graffiti was reissued in 2015, and featured bonus material containing alternative takes and previously unreleased songs, "Brandy & Coke", "Everybody Makes It Through" and "Driving Through Kashmir".
