Klang: A Tribute to Karlheinz Stockhausen is a weeklong festival celebrating the German composer's work, featuring the world premiere of Urantia and his final effort, Zodiac. Stockhausen's groundbreaking electronic opuses are scrupulously honoured by Holland's Asko Ensemble and London's Sinfonietta, and by a heaving schedule of late-night performances, lectures and master classes.
