Physical GraffitiCertified 16x platinum in the U. S., the commercial success of Physical Graffiti was equaled by its critical reception. 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 bands dynamic musical range, from the driving rock of Custard Pie and acoustic arrangement of Bron Y Aur Stomp to the Eastern raga of Kashmir and funky groove of Trampled Under Foot.
