An interview with Alex Ross:

I thought I had no choice but to write about the 20th century; it’s such an extraordinary body of work that is relatively little known, especially in terms of your average educated person who can tell a Picasso from a Jackson Pollack and has read widely in contemporary literature and knows the great books of the 20th century, but will freeze up when you mention Schoenberg and Stravinsky. The thing is, they know the music, they know the sound of the music‚Äîthey’ve been exposed to it in one form or another on film soundtracks, in concerts, or on CDs‚Äîbut they don’t necessarily know where this music came from, and how it all fits together, and how one composer affects another or reacts to another.
