Enjoy!
"The hundred dollar nap" by Dan Visconti ponders why people sleep at classical concerts and what could (should?) be done about it.
"The boos for Tosca reverberate" by Daniel Wakin relates the strongly mixed reception to the Metropolitan Opera House's gala opening performance of Puccini's Tosca
"The curse of the recital" by Kyle Gann, citing Robert Ashley's views on the politics of recitals and recital-going.
The future of classical music? Greg Sandow's book-in-progress about, well, the future of classical music.
Enjoy!
