Forgive me if this has been discussed in another thread, but I was wondering -- why, in all the many mentions of Glazunov, has Tchaikovsky not been mentioned as well? In the middle portion of their free dance when the piano music suddenly picks up speed and they do their twizzles, a brief portion of Tchaikovsky's Piano Concerto #1 is played. I checked a recording of it last night to make sure I was right, and yes -- it is definitely Piano Concerto #1.
As a classical musician, personally I found that sudden insertion of Tchaikovsky a bit jarring. I did not feel that it blended with the rest of the music at all. The Scriabin and the Glazunov complemented each other IMO, but at no point in any article about their music choices did I ever see Tchaikovsky mentioned, and I found that very strange.
It's sort of like when people kept saying that Gordeeva and Grinkov skated their '94 LP to "Moonlight Sonata" when in reality the opening of their LP music was the Pathetique sonata.
