A couple of late recommendations for the evening:
On the Front Porch of the Center for the Study of the American South, on West Franklin St in Chapel Hill (next to the UNC President's house), a UNC student jazz band will play 5:30-7p. They should be good & deserve support.
If you want a preview of an Art of Cool 2015 Festival act, the progressive band Snarky Puppy is at the usually-not-a-jazz-venue Southland. Where doesn't matter; what does.
And, the next night at Southland, the Camel City Collective plays its jazz-inflected mix. No that's not Joe Camel's band. It's a group that included jazz guitarist Scott Sawyer in it
