Fuse Gallery features some of the foremost names in underground and low brow art in New York. The shows, whether they be of a single artist or group shows, are ALWAYS fantastic. The space is nice, well lit, and not too big - but they always fill the walls with work.
Located in the back of Lit bar, you're always just a stone's throw away from a reasonably priced drink or pint of beer, so you can peruse the work then slouch at a wooden table in a low-lit corner to talk about it. If you time it right you can also head downstairs to the performance room and catch whatever band is booked for the night.
