After a two-year recording gap (the longest in their recording career up to that point), Led Zeppelin followed the rampant eclecticism of HOUSES OF THE HOLY with the embarrassment of riches that is PHYSICAL GRAFFITI. One could be forgiven for thinking of this expansive double-length set as Zeppelin's WHITE ALBUM. It's a great schizophrenic beast, the first side containing the most concentrated dose of pure hard-rock energy the band had delivered since their first two albums, and the second showing off the more subtle nuances of their talent.

This is really Jimmy Page's album, from the masterfully moody Eastern setting of "Kashmir" to the poignant liquidity of "Down by the Seaside" and the furious riffing of "Trampled Under Foot." The 1950s-style rocker "Boogie with Stu" (featuring Stones pianist Ian Stewart) and the rural romp "Bron-Yr-Aur" add yet more colors to the spectrum of what may be the most emotionally satisfying album in the Led Zeppelin canon.
