This show is being postponed to August 23. Original tickets will be valid for the new date. If unable to attend the August date, ticket holders have until April 7th to request a refund. 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!
