Legendary rockers Led Zeppelin are digging a little deeper in the vaults as plans for an expanded edition of 1997's BBC Sessions release are underway. The set, now titled The Complete BBC Sessions, will be available in a variety of formats on Sept. 16 through Atlantic/Swan Song. To whet your appetite, a previously unreleased song titled "Sunshine Woman" has been made available ahead of the street date.

Though Led Zeppelin may have been at the forefront of heavier rock and roll, the band's sound was initially rooted in the blues and one listen to "Sunshine Woman" and you can start to trace those influences. This live version of the song opens on a swinging piano part, while harmonica wails slip in amidst the funky guitar, bass and drum play. And there's no mistaking Robert Plant's powerful pipes on the track.

"Sunshine Woman" is one of eight previously unreleased tracks that have been added to the now three-disc collection. Newly released renditions of Zeppelin standards "Communication Breakdown" and "Dazed and Confused" are among the fresh offerings, as are the songs "What Is And What Should Never Be," "I Can't Quit You Baby" and "You Shook Me."

As stated, Led Zeppelin's Complete BBC Sessions arrives on Sept. 16. Check out the newly updated track listing below the player for "Sunshine Woman."
