In the 2019/20 season, the Alte Oper is focusing its FOCUS on one of the most important exponents of historical performance practice and presents a three-part portrait of the Flemish sound researcher and performer Philippe Herreweghe. He is regarded as one of the central figures of historically informed performance practice – although he has long since moved from the 18th century further into the past as well as into later epochs up to classical modernism.
