Kansas City’s massive new performing arts center will be many things to many local arts organizations, or at least that’s the assumption. Among the individual components of the PAC will be a concert hall for the exclusive use of the Kansas City Symphony. The orchestra is grateful for having been included, but complaints are mounting about the small size of the hall, and some KCS staffers are wondering if the orchestra could ever hope to make money, or grow as an organization, in a hall with only 1,200 seats.
