The deluxe edition of the group's sixth studio album arrives 40 years to the day after the original debuted in February, 1975. As with the previous deluxe editions, Physical Graffiti has been newly remastered by guitarist and producer Jimmy Page and is accompanied by a disc of companion audio comprising previously unreleased music related to the original release. The companion audio disc that accompanies the deluxe edition of Physical Graffiti has seven unreleased tracks, including rough mixes of In My Time Of Dying and Houses Of The Holy, as well as an early mix of Trampled Under Foot called Brandy and Coke. All the unreleased companion tracks offer fans a chance to hear well-known songs from a different perspective, including the Sunset Sound mix of Boogie With Stu and Driving Through Kashmir, a rough orchestra mix of the band's eight minute opus Kashmir. Also featured is Everybody Makes It Through, a strikingly different early version of In The Light with alternate lyrics.
