The indie-rap label Def Jux is having a bit of a revivalist moment since its lamented 2010 hiatus, with label boss El-P's crossover success in mainstream and hipster circles. So now's an excellent time to get thee to a reunion of Cannibal Ox, another stalwart of the label known for its noisy sonics and blistering mike work. The Roxy, 9009 Sunset Blvd., West Hollywood. 8 p.m. Thu. $15. theroxyonsunset.com.
