The year's most feverishly anticipated musical event – at least for rock fans of the Napster era – is the return of bracing post-hardcore five-piece At the Drive-In. Not a great time, you'd think, for ATDI duo Omar Rodríguez-López and Cedric Bixler-Zavala to release a sprawling, unashamedly proggy concept album with their other band. Still, such is their wont, and those who tough it out will find more to admire in Noctourniquet than its bloody-mindedness. Sonically capricious in the best possible way, it takes in rasping electro, hardcore riffing, rock-opera camp and continues to throw up new surprises with every listen.
