The East Village’s Sidewalk Café has been a haven for artists working the margins of New York music for close to 30 years now. Randomly dropping by can be risky: Not every performer is the world’s next Beck (to cite one artist who rose through antifolk’s ranks). A smart time to pop in is during the Antifolk Festival, which takes over the club for a week or so every February. This year's slew of performers includes Larkin Grimm (Feb 22), Jason Trachtenburg (Feb 23), A Brief View of the Hudson (Feb 27) and Debe Dalton (Feb 28). Check sidewalkny.com for the complete lineup.
