These Texan psychedelic punks’ full-length debut is one of their most viscerally disturbing releases. Vocalist Gibby Haynes’ distorted caterwauling and incomprehensible lyrics draw you in, but soon make you regret your curiosity, and the band — guitarist Paul Leary, soon-to-depart bassist Bill Jolly, and drummers King Coffey and Teresa Nervosa — pound and roar around him. “Dum Dum” borrows the tumbling rhythm of Black Sabbath’s “Children Of The Grave,” and “Concubine” and “Cherub,” with their throbbing postpunk bass and warped guitar, are both hypnotic and horrifying in an almost existential way, like being trapped in a small, locked room with someone whose psyche is dissolving before your eyes.
