How better to close out Jazz Appreciation Month than with two untamed masters of the form — and the formless. Frequent collaborators and free-jazz improvisational geniuses, Brötzmann, a German saxophonist and clarinetist, and Drake, a Monroe-born, Chicago-bred drummer, reteam for their first U.S. tour as a duo in more than five years. Call for ticket information.
