I'm gonna say Agent should check out The Flying Luttenbachers. I remember saying something about them to him once, but I don't know if he ever followed up on it.
Their sound varies from album-to-album: spazzy no wave (Revenge of the Flying Luttenbachers) to abrasive free jazz (Destroy All Music) to the so-called "brutal prog" style of their most recent releases. My favorite of these—and their best album, I think—is Infection and Decline, a monstrously thick slab of noise, consisting of band mastermind Weasel Walter's hyperspeed drumming and two bassists armed with a shitload of effects pedals. Their newest one is Systems Emerge From Complete Disorder, which is sonically similar, but with a lot more instrumentation (guitars and pianos and such). Oh, and allmusic describes that album as "some kind of unholy marriage between Magma's aggressive, spiky '70s prog, the untrammeled anarchy of a European free improv set from the late '60s, and the pummeling aggression of modern-day Scandinavian death metal," which can just as well describe Infection.
And here's the band circa Infection and Decline (their line-up changes constantly; Walter, on the far right, is the only original member):
