Hunter's focus is a more jazz-oriented variant on the typical jam-band rock/ funk fusion; his unique guitar style and tone have led him to collaborate with a diverse array of artists including D'Angelo, John Mayer, Mos Def and Norah Jones. He performs two sets tonight in duo format with drummer Eric Kalb, who's pounded out beats for Sharon Jones and John Scofield. $12–$15/ 9:30 p.m. —Spencer Griffith
