Physical Graffiti is the sixth studio album by English rock band Led Zeppelin, released, February 24th, 1975, and mixed in-part at Electric Lady Studios. Featuring a broad range of musical styles, many of these songs were treated as forays into new individual directions. Returning after a two-year hiatus, this was Zeppelin’s second most commercially successful release, selling eight million copies in the United States alone. In 2006, the album reached platinum 16 fold in the US.
