Since its creation in 1975, IO has presented 112 operatic productions representing the work of 32 different composers. For each opera, the company performs in its original language with English surtitles projected above the stage. Renowned touring singers are featured, along with the IO Chorus and either the Indianapolis Symphony or the Indianapolis Chamber Orchestra — both conducted by long-term IO artistic director James Caraher. Clowes Memorial Hall (4600 Sunset Ave.), with its 2200 seats, hosts IO’s full-scale productions while the Basile Opera Center (4011 N. Pennsylvania St.) is the venue for small, intimate opera presentations. A proactive audience development component begins with IO's acclaimed Music!Words!Opera! education program in cooperation with area schools. This program involves the study and creation of works in opera.
