Don’t call Duncan Sheik a one-hit wonder, even if the only song of his you can readily name is the 1996 smash single “Barely Breathing.” You’re humming that tune now, aren’t you? It gets in your head, right? While he’s not cranking out pop singles these days, Sheik has hardly been sitting on his hands. For the past decade, he’s been composing the scores to massively successful Broadway musicals, including Spring Awakening. On his current tour, he’s with a band and playing from both his solo albums and his musicals; maybe he’ll give us a preview song from the soon-to-arrive American Psycho musical.
