A prolific composer for ensembles and more than 35 films (Clockers, Cadillac Records), Blanchard makes his operatic debut with two workshop performances, directed by James Robinson of Opera Theatre of Saint Louis, where Champion premieres next June. “Opera Fusion” is an extraordinary collaboration between CCM’s Opera Department and Cincinnati Opera that offers composers and librettists a 10-day workshop for new works. The creators welcome audience feedback, and you can do that at a reception following Sunday’s performance. Tickets are free but must be procured in advance. 8 p.m. Saturday Oct. 27 at CCM’s Patricia Corbett Theater, 513-556-4183; 3 p.m. Sunday Oct. 28 at SPCA Mayerson Theater 513-241-2742.
