When I set up this site last year, one of my first links was to www.schoenberg.at, the website of the Arnold Schoenberg Center in Vienna. You won't find a more comprehensive online documentation of a composer, maybe of any artist in any medium. And the site has continued to grow over the past year. Schoenberg WebRadio, the audio portion, now offers dozens of historical items, including a flavorful recording of Schoenberg conducting the second movement of Mahler's Second Symphony. Schoenberg Jukebox allows you to listen to the composer's entire output. And, for the musicologically inclined, most of Schoenberg's music manuscripts are now available for viewing.
