Inhalt: In 1977, after three years of Halloween at the Felt Forum, Zappa moved to the Fillmore East–style atmosphere of the Palladium (formerly the Academy of Music). He also added shows to the run: six marathons over four nights, with the last two concerts on October 30th and 31st hitting the three-hour mark without intermission. As Zappa told the packed and delirious crowd early on the 31st, introducing the helium falsetto of an original Mother, guest vocalist Roy Estrada, in a "glam-rock opera" about a sexually aroused rubber mask: "You don't want to have a regular Halloween, do ya? You want the best. You deserve the best. You're gonna get the best." (David Fricke auf rollingstone.com)
