New Orleans is known for its musical innovation, as well as the grinding hustle of its musicians' lives. It's the yin and the yang to the reality of the lifers: No matter how talented or visionary you are, you gotta hustle and play night after night. One band that epitomizes that ethos is The Nth Power, a supergroup soul trio of working players centered around the powerful drumming of Nikki Glaspie, human rhythm machine for Ivan Neville's funk powerhouse Dumpstaphunk, as well as a touring drummer for hire for Beyoncé. I've seen Glaspie play many times with a variety of acts and she always brings the fire. Expect nothing less from her soul act, with bassist Nate Edgar of John Brown's Body-fame and guitarist-singer Nick Cassarino. For $15? At 9 p.m.? This show is an easy one to figure out.
