Two CD live archive release. This Vaulternative Records concert release finds Zappa and band at the Uptown Theater, Chicago, Ill - September 29, 1978. Of the two shows played that evening, the late show is captured here in it's entirety. As you would expect, the concert delivers with a good blend of fan favorites, blistering guitar solos, audience participation, on-the-spot improvisations and stellar playing from a talented band line-up.
