Does any Led Zeppelin fan, even the most rabid, need five live versions of “Communication Breakdown” on one album? Enter: The Complete BBC Sessions, a three-disc update of the band’s archival set of recordings from 1969 and 1971. Jimmy Page, having already cleared the Zeppelin vaults with a slew of extra-padded reissues, manages to dust off some extra dusty BBC rarities—pushing the collection into overkill territory. This hyped third disc includes three grainy tunes (“I Can’t Quit You Baby,” “You Shook Me” and the sole performance of honking, piano-led “Sunshine Woman”) tracked during a radio broadcast in April 1969. The rest? More solid but non-noteworthy BBC cuts, mostly of songs available on the first two discs. That said, the uninitiated should seize this opportunity to explore the original material. Disc one, which highlights four 1969 BBC sessions, finds The Golden Gods in prime early form: John Bonham’s tom-tom excursions and Page’s psychotic noise push “Whole Lotta Love” into more demonic territory, while their infectious run-through of Robert Johnson’s “Traveling Riverside Blues” is propelled by the ghostliest slide-guitar riff ever laid to tape. Disc two teases a blistering 1971 London concert, showcasing their majestic two-year evolution. While some of the softer performances (mandolin-led ballad “Going to California”) are filled with clumsy transitions and jumbled vocal lines, the band sounds more propulsive than ever on the heavy numbers—including Led Zeppelin II’s “Heartbreaker,” beefed-up by John Paul Jones’ fluid bass fills. The Complete BBC Sessions doesn’t deepen Led Zep’s legacy—but they, the greatest hard-rock band in history, don’t need it to.
