Oberhofer @ 4Knots (more by Amanda Hatfield)
Oberhofer, whose official upcoming tour has him/them headlining Bowery Ballroom in March, has been playing some suprise local show lately. The next, though not exactly a secret, happens tonight (2/14) at 285 Kent and tickets are on sale. Slowdance, Night Manager, and Bear Ceuse are also on the bill.
Alternatively, if you're 21+, you can head to Pianos to see a free show by Devin and others.
