en Cuevana 3. Donnerstag was the first completed work of the gigantic seven-opera cycle Licht by German composer Karlheinz Stockhausen. Composed over a span of 25 years and lasting nearly 30 hours in total, the cycle offers up a wide-ranging, experimental take on theology, time, and the nature of the universe. In Donnerstag, the protagonist Michael comes to life in three different guises, played by a singer, a dancer, and a trumpeter as he passes from an impoverished childhood to an artistically successful adulthood and, finally, to the celestial realm as an archangel.
