For the first-time ever, Zappa's historic October 31 Halloween night concerts and the closing November 1 show recorded live at The Palladium in 1981 will be released as a gigantic six-disc box set featuring 78 unreleased live tracks totaling more than seven hours of live performances from three complete concerts. Available October 2 via UMC, the expansive release is the next in the acclaimed costume box set series which began with the Halloween 77 box set in 2017 to chronicle these iconic concerts and celebrate Zappa's love of Halloween. The specially-designed costume box will include a Count Frankula mask along with a red and black cape so fans can dress like vampire Frank Zappa for Halloween or display alongside their FRANKenZAPPA mask and gloves from last year's Halloween 73 box or the retro mask and costume of the maestro himself from the inaugural release. Fully authorized by the Zappa Trust and produced by Ahmet Zappa and Zappa Vaultmeister Joe Travers, the concerts have been newly mixed from the original Ampex 456 2-inch 24-track analog tape masters by Craig Parker Adams in 2020. This king-size offering also includes a 40-page booklet with rare photos from the event by John Livzey (Livzey.com) and new liner notes by touring band member Robert Martin, Vaultmeister Joe Travers and super fan-in-attendance Gary Titone who pens a remembrance of the shows. In addition, a 1CD version titled Halloween 81: Highlights From The Palladium, New York City will also be released, featuring performances from all three shows along with an exclusive track, “Strictly Genteel,” from the November 1 show not included on the box set. It will be packaged in a jewel case with liners by Travers.
