Marry Me, the 2007 debut from St. Vincent — a.k.a. Annie Clark, a multi-instrumentalist who has played with Sufjan Stevens and the Polyphonic Spree — was a carefully crafted, well-reviewed album that sort of went nowhere. But Marry Me didn’t have “Actor Out of Work,†the lead single from next month’s Actor; this neat little gem — all chugging guitars and Clark’s elegant vocals — sounds to us like a breakout waiting to happen. The video’s not too shabby, either: In a giant empty warehouse, and in between casting subtle quizzical looks and over-enunciating, Clark auditions actors, who cry on demand.
