What do you get when you combine rock and classical guitar with Malian tunings? The sound of Habib Koité. The Malian guitar master, whose artistry Bonnie Raitt ranks alongside Jimi Hendrix and Stevie Ray, will be playing with his band Bamada at the Raven Performing Arts Theater in Healdsburg. The all-ages world music show will be held on October 30 at 7:30 p.m. Tickets are $30 in advance, $35 at the door, and are available at raventheater.org.
