CMJ Day 4

We're all over the place tonight. Here are our picks for how to spend day four of CMJ:

Catch the haunting tunes of Angus and Julia Stone at The Bell House, Sean Lennon's band The Ghost of a Saber Toothed Tiger at Union Hall, or a 16-act marathon (of course) at Spike Hill Tavern in Williamsburg.

Spike Hill Tavern [184 Bedford Ave. at N. Seventh Street in Williamsburg, (718) 218-9737)], all day; The Bell House [149 Seventh St. between Second and Third avenues in Gowanus, (718) 643-6510], 7:30 pm; Union Hall [702 Union St. at Fifth Avenue in Park Slope, (718) 638-4400], 8 pm.
