The boundary-testing Welsh comedy collective Goldie Lookin Chain send up white working-class culture and the music industry with sly self-awareness, rambunctious energy, and a stand-up's command of silly voices. Over jaunty clarinets and boom-bap breaks, "Self Suicide" considers dying young as a record-sales strategy, and the satiric "Guns Don't Kill People, Rappers Do" mocks anti-rap crusaders over a surprisingly funky track packed with knowing hip-hop references. Judging by the old-school electro on "Roller Disco," no matter how off-the-wall the jokes are, the boys are dead serious about their beats.
