Stockhausen Festival in Amsterdam

Source: The New York Times.

There was a palpable buzz on a recent afternoon in the Gashouder, a big, round former industrial building in a park on the west side of Amsterdam. A buzz, that is, beyond the four helicopters whose steady drone was being relayed through banks of speakers set up to rehearse a crucial part of “Aus Licht,” a marathon performance of selections from Karlheinz Stockhausen’s eye-poppingly extravagant, never-fully-performed, seven-opera, 29-hour “Licht” cycle. (Divided into three hefty evenings, it runs from May 31 through June 10.)
