Trainspotting’s soundtrack was one of the more impactful in cinema history: it introduced a generation to Iggy Pop and formed a perfect document for UK music’s twin signature movements in the ‘90s: Britpop and rave. Much like its celluloid counterpart, the stars return here (The Prodigy hand “Lust for Life” a colossal do-over and Underworld rewire “Born Slippy”), but it’s the new talent that takes center-stage. Wolf Alice’s sublime “Silk” connects to the movie’s pulse and Young Fathers’ three contributions capture its jagged, uneasy atmosphere.
