If, as in provincial New York, there are no live Mahler events in your town on the anniversary of his death, the Internet is ready to pick up the slack. Medici.tv is offering the complete symphonies with the Orchestre de Paris under Christoph Eschenbach. (Free with registration.) Arte and MDR will provide live webcasts from the Mahler Festival in Leipzig, with performances by the Gewandhaus Orchestra, the Vienna Philharmonic, the Concertgebouw, the New York Phil (also live at nyphil.org on 5/23), the Dresden Staatskapelle, the London Symphony, the Zurich Tonhalle, the Mahler Chamber Orchestra, the Bavarian Radio Symphony, and the MDR Symphony. And for ten euros you can buy access to the Berlin Philharmonic's special concert under the baton of Claudio Abbado, with Anne Sofie von Otter and Jonas Kaufmann singing Das Lied von der Erde. On May 20, NDR in Hamburg will broadcast an Eighth Symphony with the ubiquitous Eschenbach conducting; beforehand, you can hear the premiere of Nathaniel Stookey's Mahl/er/werk, a kaleidoscopic collage of Mahler fragments.
