Although he’s toured with Aretha Franklin, Van Morrison and Etta James, James Hunter still continues to play shows at small venues like Sweetwater Music Hall. Hunter spent most of his early career playing at clubs in London, so it’s no surprise that he’s happy to return to his roots. Hunter’s style is so unique that even Van Morrison took notice and sang backup vocals on his songs “Turn on Your Love Light” and “Ain’t Nothing You Can Do.” The energy delivered by Hunter’s new group, the James Hunter Six, is more than most bands half their age. See the Grammy-nominated singer on Saturday, May 25, at Sweetwater Music Hall. 19 Corte Madera Ave., Mill Valley. $22. 8pm. 415.388.3850.
