Last weekend the Wordless Music Orchestra gave the US premiere of Jonny Greenwood's Doghouse for orchestra and string trio. Also on the program was Philip Glass' Symphony No. 4 "Heroes" and Gyorgi Ligeti's Chamber Concerto for 13 Instruments. I'd pay money to hear that. Here are live recordings from the show.
