Led Zeppelin has announced that it will release a 7″ vinyl single on Record Store Day on April 21.

The band announced that the single will feature two previously unheard mixes produced by Jimmy Page: the Sunset Sound Mix of “Rock And Roll” on the A-side and the Olympic Studios Mix of “Friends” on the B-side.

Led Zeppelin magazine Tight But Loose published the full press release, which goes into more detail on the content of the release:

“Limited Edition 7-Inch Single, Produced By Jimmy Page.

To Be Released On Record Store Day Featuring Unreleased Versions Of ‘Rock And Roll’ And ‘Friends’

Available April 21 – Exclusively At Independent Music Retailers

In advance of Led Zeppelin’s 50th Anniversary celebration, slated to commence this September, the band will whet fan’s appetites with their first ever release for Record Store Day on April 21. The limited edition 7-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 their 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.”

And Record Store Day shared these renders of the release on Facebook:

Jimmy Page has previously spoken of his wish for a Led Zeppelin release on Record Store Day

Page said in an interview with Tight But Loose magazine in 2015 that he could release studio material on Record Store Day “in five year’s time.”

And in the press conference for the final Led Zeppelin remasters around the same time, Page reportedly said “as far as the studio side of things, this is it, unless something might pop up on international Record Day or something like that. But it will be a long way off.”
