Graewes first opera, Kopenhagen (Copenhagen), a commission from the Cologne Opera, was premiered in 2003. Graewe currently teaches at the Hanns Eisler Hochschule in Berlin and at the Musikhochschule in Cologne. His chamber orchestra composition Anspielung (Allusion) refers to a 15-measure passage from Brahms Intermezzo, Op.76, Nr. 1, without literally quoting from it. In this case, the music is not made up of variations in the formal sense, but rather a calling-forth of sonic atmospheric characteristics of the Brahms piano composition, projected into a 10-piece chamber orchestra.
