Led Zeppelin launched its new Swan Song label with the double-LP PHYSICAL GRAFFITI. Recording, which began in December 1973 and concluded in July 1974, took place in numerous locations, including Olympic Studios in London, Ronnie Lane's Mobile Studio and The Rolling Stones' Mobile Studio.

Recorded on the run as it were, PHYSICAL GRAFFITI codifies the stylisitc breakthroughs of Led Zeppelin's first five albums. The most well-known of its 15 tracks is "Kashmir," a typically mystical, Eastern-flavored rocker, fleshed out by Page's orchestral flourishes and Bonham's big-foot backbeat. John Paul Jones makes extensive use of electronic keyboards on "In The Light," and Robert Plant's turn on "Black Country Woman" is a sexy, playful nod to the Mississippi Delta.

"The Wanton Song," "Trampled Under Foot" and "Houses Of The Holy" reflect Zeppelin's infatuation with funk, but with Zeppelin's distinctly hard-rock interpretation. "Bron-Yr-Aur" is a shimmering solo acoustic guitar excursion by Page, while "Boogie With Stu" is a charming showpiece for pianist Ian Stewart, a Rolling Stones sideman, with Page taking a very Chuck Berryish turn on mandolin.

The album was released in the U.S. on February 24, 1975 and in the U.K. on the following day.
