CD Soundsystem may be no more, but former frontman James Murphy, 43, is as busy as ever: He's DJ'ed, designed an actual sound system for McIntosh Laboratory, and made a short film with Ron Howard—all while overseeing DFA Records (home to bands like the Rapture and Holy Ghost!). This month, you can hear his handiwork on Arcade Fire's new album, which he produced, and on Broadway, where he scored the revival of Harold Pinter's Betrayal, starring Daniel Craig and Rachel Weisz. Here, we ask the eclectic impresario where his own tastes lie.
