[4] In 2005, the company began offering off-season productions in October which focused on suspense-driven, "spooky" repertoire including Gian Carlo Menotti's The Medium, Benjamin Britten's The Turn of the Screw, Béla Bartók's Duke Bluebeard's Castle and Puccini's Il tabarro.
[1][7] That season marked the welcoming of guest conductor Kostis Protopapas, of Tulsa Opera, to conduct a double bill of Suor Angelica and Gianni Schicchi.
Union Avenue Opera's 2013 season will include Puccini's Manon Lescaut, Wagner's Die Walküre (in an adaptation by British composer Jonathan Dove) and Leonard Bernstein's Trouble in Tahiti.
In August 2011, Union Avenue Opera presented the Missouri premiere of Jake Heggie's Dead Man Walking to great critical acclaim.
In conjunction with the production, UAO and Union Avenue Christian Church invited anti-death penalty activist Sr. Helen Prejean, CSJ to speak on the opera and her ministry.
The company offers a variety of lectures and behind-the-scenes events in which patrons learn about upcoming productions, hear musical excerpts performed by UAO artists, listen to presentations, view costumes and tour sets in a relaxed atmosphere.
