MX-80 Sound is one of the real oddities in American music, emerging from the mid-'70s proto-punk zeitgeist. Hailing from Bloomington, Indiana, MX-80 Sound is lead by guitarist Bruce Anderson and defies simple classification with relentless riffs, dual drummers and vocalist Rich Stim's absurdist prose and dizzying sax. Assimilating the avant-rock of Captain Beefheart and conjuring the ghosts of Albert Ayler, MX-80 Sound evokes what free jazz would sound like if born in Bloomington.
