Altstaedt’s unwavering commitment to bringing classical music to wider audiences has led him to explore new avenues alongside his conventional engagements. For Arte and the Ufa Filmnächte Berlin, he recorded film music for Carmen by Ernst Lubitsch. With Ensemble Resonanz, he has presented Faust by Friedrich Wilhelm Murnau at the Salzburg Festival and, most recently, The Merry Widow by Erich von Stroheim at Hamburg Elbphilharmonie and Vienna Konzerthaus.
