Reissue of this title from genre-defying music icon Frank Zappa and his Mothers Of Invention. Ahead of their time? No kidding. Another archival release, from 1993, this documents the early Mothers Of Invention as they perform live, along with members of The BBC Symphony Orchestra, at London"s Royal Festival Hall in October of 1968. FZ spent some time in court dodging archaic British obscenity laws as a result of these very shows, so listen with some respect.
