The early-mid ‘80s had their share of insane combos -- The Birthday Party, Black Flag and Minor Threat had the raw power to melt your mind in seconds. SWANS, Einsturzende Neubauten and Big Black created enough overwhelming sonic pressure their sounds might actually flatten you. And Sonic Youth displayed such a dizzyingly unpredictable mix of art, pop culture and violence you’d sometimes leave their shows drooling. The Buttholes shared elements with all of these groups, but added an insane psychedelic edge and a propensity for bizarre spectacle.
