Trafficking in a free-flowing blend of jazz, hip-hop and Afrobeat, the Hypnotic Brass Ensemble can resemble the world's funkiest marching band one minute, an unhinged New Orleans funeral procession the next. The group's recent collaborators have included Maxwell, Erykah Badu and Gorillaz, but this performance will feature an appearance by the group's patriarch, veteran Chicago trumpeter and Sun Ra collaborator Phil Cohran, who is father to the ensemble's eight brothers. The Exchange, 618 S. Spring St. L.A. 8 p.m. Thu. $30. exchangela.com.
