If you thought last week’s show was crazy, you’ll need to plug your ears and hide from this one. The first half is remarkably sedate: an unreleased Negativland live recording from their 2012 tour, with Crosley Bendix explaining why there can never again be any original music, followed by Princess Wei’s reading of a touching rant by Rev. Chocolate Velvet (with music by The Flyin’ Ryan Brothers). But then Dave calls in, and Stang starts sneaking especially ear-futtering stereo LeMurian clips into the mix. It gets more chaotic, psychedelic and surreal than usual — OLD SCHOOL Hour of Slack! Then, Dr. Sinister arrives. AIEEE!
