Since 2003, the modern opera house is home to Theater Erfurt and its Philharmonic Orchestra. The "grand stage" section has 800 seats and the "studio stage" can hold 200 spectators. In September 2005, the opera Waiting for the Barbarians by Philip Glass premiered in the opera house. The Erfurt Theatre has been a source of controversy. In 2005, a performance of Engelbert Humperdinck's opera Hänsel und Gretel stirred up the local press since the performance contained suggestions of pedophilia and incest. The opera was advertised in the programme with the addition "for adults only".[citation needed]
