The Dayton Performing Arts Alliance (DPAA) Inaugural Gala at the Schuster Center in downtown Dayton, Saturday, October 5, 2013. The DPAA is the newly formed alliance between the Dayton Philharmonic, the Dayton Opera and the Dayton Ballet. If not one of a kind, it's at the forefront of a new trend across the country, and shows great promise to improve the situation for not only these groups, but the arts in Dayton.
