Arguably the most infamously named band in the annals of popular music — for years, radio found their moniker unspeakable, and the press deemed it unprintable — Butthole Surfers long reigned among the most twisted and depraved acts ever to bubble up from the American underground. Masters of calculated outrage, the group fused the sicko antics of shock rock with a distinct and chaotic mishmash of avant-garde, hardcore, and Texas psychedelia; sleazy, confrontational, and spiteful, songs like The Revenge of Anus Presley, Bar-B-Q Pope, and The Shah Sleeps in Lee Harvey Oswalds Grave seemed destined to guarantee the Buttholes little more than a lifetime of cultdom. Yet, by the mid-90s, they were left-field Top 40 hitmakers, success perhaps their ultimate subversion of mainstream ideals.
