“We wanted to end up where we started,” said Charlotte Caffey, and what she meant was Los Angeles. That’s the city in which Caffey and her bandmates formed the Go-Go’s in 1978, and it’s the place they returned Tuesday night for the final show of a month-long farewell tour at The Greek. True to the economical spirit of the music, the Go-Go’s didn’t drag out this goodbye with long speeches or a corny video montage. From the band’s opener, “Vacation,” to its closer, “Head Over Heels,” it was onstage for less than 90 minutes — and that included two encores.

Featuring a cast that includes Sonic Youth's Kim Gordon and Thurston Moore, Mike Watt of the legendary hardcore band Minutemen, and Pettibon himself, this deadpan narrative pays dubious homage to the 1960's radical underground. In this crudely rendered home video of a commune of stoned revolutionaries, the cameras are hand-held, the edits in-camera, and the dialogue is wryly on-target. Pettibon's band of outsiders reenacts a countercultural moment defined by rock music, drugs, and ideological paradox — and in so doing, captures their own late-80's West Coast grunge milieu as well.
