More than a decade after their inception, the Brooklyn-born Medeski, Martin & Wood have achieved an unlikely status among music fans, earning both a devoted jam-band following and respect from the jazz community for their undeniable chops and musical creativity. On their recently released Radiolarians III (the final installment of a trilogy), MMW continue to sidestep convention. Instead of writing and recording new songs in the studio and then playing them live, they introduce material to audiences onstage before committing it to record. The group performs at 8 p.m. at the Kent Stage (175 E. Main St., 330.677.5005). Tickets: $30. — Ernest Barteldes
