From NYTimes.com:
Stockhausen died in 2007, without having seen “Licht” staged in its entirety. But his work has found new life at the Cologne Opera, which in recent weeks presented the culmination of the cycle, “Sonntag” (“Sunday”). To house the production the company built two theaters within the cavernous Staatenhaus am Rheinpark, part of the city’s exhibition center.
