Speaking, as I was in the Erling Wold entry, of trying to get information about new music in the ’70s, I remember once I was confused about something that composer Henri Pousseur had written in an article in Die Reihe, the then-awe-inspiring journal of the Darmstadt crowd. My friends and I, feeling entitled to some clarification, stayed up half the night trying to find a long-distance operator in Liege who spoke English, trying to get Mr. Pousseur’s home number from information. Today, we’d be able to go to henripousseur.com and send him an e-mail. Once, at the June in Buffalo festival, a bunch of us tried to get Stockhausen on the phone, too.
