The Zappa Family Trust and Zappa Records are offering the opportunity for fans to license their own copies of Frank Zappa and the Mothers of Invention’s Roxy By Proxy. For a $1000 licensing fee, anyone can purchase a master duplication copy of the album, which includes 76 minutes of unreleased master recordings from the December 9-10, 1973 performances at The Roxy in Los Angeles. The compilation features the songs “Inca Roads,” “Penguin in Bondage,” “T’Mershi Duween,” “Dog/Meat,” “RDNZL,” “Cheepnis & Dupree’s Paradise,” “King Kong,” “Chunga’s Revenge” and more. Those who purchase the masters will also be provided with liner notes and packaging artwork so they can duplicate the CDs to sell at any price, though a $1.20-per-CD mechanical royalty will be paid back to Zappa Records. The offer is available now through December 28. Interested parties can find more details here.

Proceeds from the sale of the masters will be used to complete The Roxy Performances film that Zappa fans have been waiting decades to see. As previously reported, the film will include footage from Zappa’s legendary December 10-12, 1973 shows at the The Roxy. The concerts featured a stellar line up that included George Duke on keyboard, Don Preston on synths, Ruth Underwood on percussion and Chester Thompson on drums. The shows were all captured on film by multiple cameras, and there were multi-track recordings of all of the audio as well, though very little of it has been released thus far.
