Rough Mix was initially released in September 1977 while The Who were on hiatus and was a collaboration with Small Faces bassist the late Ronnie Lane and features contributions from Who bassist John Entwistle, Eric Clapton, and Rolling Stones drummer Charlie Watts amongst others.

These limited-edition black vinyl versions have been mastered by long-time Who engineer Jon Astley and cut for vinyl by Miles Showell at Abbey Road Studios with a half-speed mastering technique that produces a superior vinyl cut and are packaged in original sleeves with obi strips and certificates of authenticity. Rough Mix is presented in a gatefold sleeve.
