Some twenty concerts are happening on the great man's birthday, according to the Schoenberg 150 website. Included are no fewer than four performances of Gurre-Lieder — in Montreal, Vienna, Milan, and Hamburg. (I'm now watching on an Elbphilharmonie stream of the last.) Especially notable is a pair of Schoenberg events at the National Philharmonic of Ukraine. The only American celebration listed at Schoenberg 150 is one at the Westside Conservatory in Los Angeles. Schoenberg's son Larry will be speaking, and Viennese pastries will be served. Alles Gute zum Geburtstag!
