Official Release #70. This two-disc set represents almost all of Frank Zappa's concert on January 20, 1976, at Hordern Pavilion in Sydney, Australia. The only problem is that there was only one reel-to-reel machine to record the concert, necessitating missing portions of several songs to change tapes; these gaps were replaced by excerpts from a pitch-corrected bootleg from the same tour, with an obvious drop in sound quality but little loss in continuity. This particular band – with tenor saxophonist Napoleon Murphy Brock, bassist Roy Estrada, drummer Terry Bozzio, and keyboardist Andre Lewis (in his only tour with Zappa) – has only been represented sporadically on Zappa's earlier releases.
Official Release #91. In October 1971, Frank Zappa & The Mothers of Invention played two shows in one night at New York City’s Carnegie Hall. The album, Carnegie Hall, celebrates that night's marathon – two shows (7:30 and 11:30 p.m.) with ticket prices ranging from $3.50 to $6 – featuring Zappa (lead guitar, vocals) with Mark Volman (vocals, percussion), Howard Kaylan (vocals), Ian Underwood (keyboards, alto sax), Don Preston (keyboards, gong), Jim Pons (bass, vocals) and Aynsley Dunbar (drums).
Official Release #89. By 1978, Frank Zappa's live concerts easily eclipsed those by any other rock band, due to his demanding rehearsals (in the case of this band, they worked for three months prior to touring), which not only enabled him to segue continuously from one song to the next, but also to change things with a few hand signals in the midst of a concert. This posthumously released three-CD set compiles the best performances from several early 1978 shows at Hammersmith Odeon in London, edited in the same seamless fashion as his live performances.
