Led Zeppelin returned from a nearly two-year hiatus in 1975 with Physical Graffiti, a sprawling, ambitious double album.
It captures elements of the band's personality rarely showcased elsewhere – many of the songs on Physical Graffiti are forays into individual styles. Most of the heavy rockers are isolated on the first album, with the second album sounding a little like a scrap-heap of experiments, jams, acoustic workouts, and neo-covers.
While not as consistent as the first platter, its quirks are entirely welcome, not just because they encompass the mean, decadent "Sick Again", but the heartbreaking "Ten Years Gone" and the utterly charming acoustic rock & roll of "Boogie With Stu" and "Black Country Woman".
