"Sharleena" had been previously issued as a flexi disc in Guitar Player magazine. All the songs on disc one are by the 1984 band (except for brief segments of "Drowning Witch" edited in from the 1982 tour). Disc two includes performances from various years including a section of "King Kong" taken from the December 10, 1971 Rainbow Theatre concert, performed shortly before Zappa was pushed from the stage by an audience member. Zappa's liner notes state that after he played his solo the attack happened "moments later," but in his autobiography he wrote (consistent with the memories of other band members) that the incident took place after the band had finished its encore, a cover of the Beatles song "I Want to Hold Your Hand".
The album contains performances of "Cocaine Decisions" and "Nig Biz" from a concert in Palermo, Italy on July 14, 1982. During "Cocaine Decisions", an audience riot began and police shot tear gas into the auditorium. A canister can be heard triggering near the stage, and between songs, Zappa and roadie Massimo Bassoli are heard attempting to calm the crowd down. Zappa was later reported stating, "We played for an hour and a half with tear-gas in our face and everything else, and when it was all over we went off stage and we were trapped inside this place."
