There were many tributes to composer and conductor Pierre Boulez following his death January 5, 2016, at the age of 90. Here is the NYT obituary, and I enjoyed reading the articles in the February Gramophone magazine. Just last year David Robertson of the St. Louis Symphony wrote an appreciation of Boulez for the same magazine; when we saw Robertson at a social occasion here in town, I was able to tell him the article was interesting and helpful.
When Beth and I were dating, PBS broadcasted the Ring operas conducted by Boulez, something we alluded to for a long time. So it was enjoyable to go back and re-watch Das Rheingold, with the Rhinemaidens loitering around a hydroelectric dam and Loge, as one of the YouTube watchers commented, looking a little like Riff Raff in The Rocky Horror Picture Show.
