NOURA MINT SEYMALI You can call it griot rock or desert blues, but with the ululating gale-force power of Noura Mint Seymali’s singing and the stinging, psychedelic Afro-funk lines provided by her husband, Jeiche Ould Chighaly, and the rest of her band, these Mauritanians produce a sound that’s quite their own. July 30, 7:30 p.m. Tickets: $30. Museum of Fine Arts. 800-440-6975. www.mfa.org
