The Led Zeppelin reissue campaign continues in 2015, turning the spotlight on Physical Graffiti, arriving 40 years to the day after the original debuted on February 24, 1975. Certified 16x platinum in the U.S. and generally regarded as one of the greatest double albums of all time, the original 15 tracks represent a creative tour de force that explores the band’s dynamic musical range, including key tracks “Custard Pie,” “Bron-Y-Aur Stomp, ” “Trampled Under Foot” and “Kashmir.” The companion audio disc that accompanies the deluxe edition of Physical Graffiti has seven compelling unreleased tracks.
