Over the years, Boulez would come on my various other shows (Around New York in the 1990s, Soundcheck in the 00s), but one of the most memorable visits he paid us was early in 2000. Rather than just interview him, again, I asked if he’d make a list of what he considered the ten most important pieces of music in the just-concluded 20th century. I’m not sure what I was thinking – just trying to do something different, I guess, but to my surprise and delight, he agreed. Over the course of a week, we broadcast his Top 10, two pieces each day, with Boulez himself explaining why he chose each piece. Read on to find out what he chose and why.
