A 15-year old New Yorker, David Sacks does not seem to think of Elliott Carter's piano sonata as being any more challenging than those of Beethoven or Chopin. When talented youngsters like Sacks begin to learn - and perform! - Carter's music along with the music of the 18th and 19th century masters, perhaps there is still some hope for the survival of modernist art music in America.
Just for the fun of it, you can compare Sacks' performance with a live recording of the same sonata by the much older (and vastly more experienced) New York-based pianist Ursula Oppens (b. 1944), who has been one of the most active advocates of Carter's music as well as a friend of the composer. Her performance was recorded in October 2008 at the Fraser Performance Studio, WGBH, Boston.
