In ‘Keten en Stompen’, Elmer Schönberger talks about Louis Andriessen, and about their friendship, about Stravinsky, about playing the piano together (stumping), about distant travels, about life, death, good notes and, preferably, bad notes, about drinking whiskey and playing cards (chain ). The starting point of this program about friendship are two compositions: the music for Andriessen’s film Waves and Schönberger’s musical theater Verhuisbericht.
