The limited edition seven-inch single is produced by Jimmy Page and pressed on yellow vinyl. The single will feature two previously unheard studio mixes, handpicked by Page to appear on the release: the "Sunset Sound Mix" of "Rock And Roll" b/w the "Olympic Studios Mix" of "Friends".The previously unreleased version of "Rock And Roll" provides an additional peek into the fabled "Sunset Sound Mixes" of "Led Zeppelin IV". Only two previous "Sunset Sound Mixes" have been released, the first being the version of "When The Levee Breaks" on the original album and the second the "Stairway To Heaven" mix that debuted on the 2014 deluxe edition. The previously unheard "Olympic Studios Mix" of "Friends" is a stripped-down version, without the orchestration of the final mix, offering a true fly-on-the-wall feel from the band's recording sessions for "Led Zeppelin III" at Headley Grange.Additionally, LED ZEPPELIN will release a newly remastered version of its classic live album "How The West Was Won" in multiple formats on March 23 including the first ever vinyl and Blu-ray Audio editions (with the Blu-ray containing hi-res 5.1 surround sound). The collection captures performances from LED ZEPPELIN's legendary concerts at the Los Angeles Forum and Long Beach Arena on June 25 and 27, 1972. Melded together and sequenced to replicate a single concert from beginning to end, the three-CD and four-LP collections capture the band at the height of its formidable powers.
