Product Description:
BONGO FURY turns 50! The classic collaboration between Frank Zappa and Captain Beefheart during May 1975 resulted in a flurry of new compositions, a tour, and eventually an album. Bongo Fury is made up of mostly live recordings from the Armadillo Headquarters in Austin, Texas along with a few studio recordings from the Record Plant in Los Angeles. The album is a memorable addition to the Zappa Catalog and the last to feature the band name "Mothers" before it was retired in 1976. This new 50th Anniversary Edition box set presents 5 CDs of material (roughly 80% unreleased), including studio outtakes, live tracks, plus the two Armadillo concerts complete and remixed from the original 16-track masters. Also included are unseen photos and liner notes from band member, Denny Walley, plus Vaultmeister Joe Travers. Blu-Ray features new Dolby Atmos, 5.1 mixes, and high-resolution stereo audio with bonus surround experiences from Zappa's Vault.
