Once a year, Mark "Mr. B" Braun, Ann Arbor's own wizard of blues and boogie piano music, comes together with other top piano players from around southeastern Michigan and beyond. Call it a piano summit, or perhaps a meeting of the minds! Audiences in southeastern Michigan tend to think of Mr. B as a local hero, but in fact he's well known among fans and practitioners of blues and jazz piano music all over the country and around the world. This year Mr. B will be joined onstage by Demetrius Nabors and two surprise special guests.
