Where Did Popular Classical Music Go?

Where is the new classical music? Okay, there’s lots of music being written out there. But “what is the most recently composed piece of classical music to have achieved a genuinely established place in the repertoire? I mean a piece that you can count on hearing in most major cities most years, and a performance of which is likely to bring in a large general audience. Shostakovich’s first cello concerto, written in 1959, perhaps? Even that is stretching a point. A more truthful answer might be Richard Strauss’s Four Last Songs, composed 56 years ago in 1948.”
