Led Zeppelin's BBC sessions were among the most popular bootleg items of the rock & roll era, appearing on a myriad of illegal records and CDs. They were all the more popular because of the lack of official Led Zeppelin live albums, especially since The Song Remains the Same failed to capture the essence of the band. For anyone who hadn't heard the recordings, the mystique of Zeppelin's BBC sessions was somewhat mystifying, but the official 1997 release of the double-disc BBC Sessions offered revelations for any fan who hadn't yet heard this music. While some collectors will be dismayed by the slight trimming on the "Whole Lotta Love Medley," almost all of the group's sessions are included here, and they prove why live Zeppelin was the stuff of legend. The 1969 sessions, recorded shortly after the release of the first album, are fiery and dynamic, outstripping the studio record for sheer power. Early versions of "You Shook Me," "Communication Breakdown," "What Is and What Should Never Be," and "Whole Lotta Love" hit harder than their recorded counterparts, while covers of Sleepy John Estes' "The Girl I Love She Got Long Black Wavy Hair," Robert Johnson's "Travelling Riverside Blues," and Eddie Cochran's "Something Else" are welcome additions to the Zeppelin catalog, confirming their folk, blues, and rockabilly roots as well as their sense of vision. Zeppelin's grand vision comes into sharper relief on the second disc, which is comprised of their 1971 sessions. They still have their primal energy, but they're more adventurous, branching out into folk, twisted psychedelia, and weird blues-funk. Certainly, BBC Sessions is the kind of album that will only appeal to fans, but anyone who's ever doubted Zeppelin's power or vision will be set straight with this record.
