MUSIC: Mary Timony, Georgie James and Welcome are at Mercury Lounge tonight. If you liked Q and not U you'll probably like Georgie James, the two-piece pop-rockers are half comprised of an ex member. Buy tickets here.

THEATER: Little Red Square is a sharp little theater company started by a couple of fresh-faced kids from NYU. They’re celebrating their second birthday tonight at KGB Bar before stumbling downstairs to premiere their latest venture, This Means Kill, at The Kraine Theater. (Those NYU kids know how to party!) You’re invited to help lubricate them before show-time and stick around for the results. The play, written by Chris Littler, is a whimsical noir homage set in France, where “hot-shot Dr. Bennet Venkerman thinks locating his troublesome wife Amelia will be a snap after enlisting French P.I. Rauffault; but when Bennett's brother Pierce realizes his four years of French might have got them more than they bargained for, the chase is on.” – John Del Signore

10:30pm // The Kraine Theater [85 E 4th St.] // Tickets cost $12 in advance, $15 at the door.
