Rotten Milk, Bongo Frontier

Rotten Milk — a founding member of Chicago drone band Cave — has of late been in New Orleans making experimental synth music like the meditative 2023 release manqué. Southwestern Wisconsin duo Bongo Frontier similarly bases their musical experiments around keys, but adds many other instruments along the way. What comes out can sound like just about anything, judging by the 2024 album Weakling Doodle Rides Again, released on tape by Kitschy Spirit. The most unpredictable show of the week.
