In September 1974, parts of the five shows on December 8, 9 & 10, 1973 (early and late shows on 9th and 10th) at The Roxy Theatre in West Hollywood, California were released on the double-LP set Roxy & Elsewhere, along with music recorded a few months later (on May 8, 1974, at the Edinboro State College, Edinboro, Pennsylvania and on May 11, 1974, at the Auditorium Theatre in Chicago, Illinois), with all of that material being overdubbed and remixed.
The album uses a mix from March/April 1987 by Bob Stone at the Utility Muffin Research Kitchen.
[2] Roxy by Proxy presents the material without overdubs, closer to what the audiences heard live (some songs are combinations from different shows), and is different from material released on Roxy & Elsewhere in 1974.
[3] All five shows were released in full on The Roxy Performances 7 CD box set in 2018, with audio restoration and 2016 mixes by Craig Parker Adams.
[4] All songs produced, composed and realized by Frank Zappa.
