Founded in 2012, Ruhrtriennale is a three-yearly cycle of music and arts events, which take place from August to October in Germany’s industrial Ruhr region. The prestige of staging this year’s opening production fell to Ensemble Modern, a renowned global collective of soloists, whose sound designer Norbert Ommer chose a Yamaha RIVAGE PM10 digital mixing system for the surrealist, unconventional opera Bählamms Fest.
