Miscellany: Tristan on demand, etc.

With another Bayreuth summer beginning to wind down, Micaela Baranello has a New York Times report on the current state of the festival, and Jens Laurson supplies a very thorough review of the revival of the Castorf Ring. The complete Katharina Wagner Tristan, this summer's new show, has shown up on YouTube; also, David Robertson and the Sydney Symphony have begun to stream their recent Tristan-in-concert, with Act I now available and the rest to come shortly....  Programs from the 2015 MATA Festival are now archived on Q2.... Also on Q2, Nadia Sirota hosts a Meet the Composer episode devoted to Kaija Saariaho, with a Library of Congress performance of Saariaho's Light and Matter tacked on for good measure.... The Detroit Symphony, the most tech-savvy of American orchestras, has launched a new service called Replay, archiving its popular video streams. A one-time donation of fifty dollars buys you access.... Ensemble Dal Niente, in Chicago, has announced an enticing 2015-16 season; the U.S. première of Stefan Prins's Generation Kill is on the schedule, as well as world premières by Johannes Kreidler, Natacha Diels, Kirsten Broberg, and Ben Sutherland, among others.... On Sept. 7, Annie Gosfield will have a semi-retrospective concert at The Stone in NYC.
