Let's hear it for teachers who make recordings of different intepretations for their students! Can't be too many of them around.
My teacher often makes me CDs filled with various performances of one piece that I'm working on, including things like Beethoven's sonatas, Rachmaninoff's preludes, Chopin's études, and Liszt's Hungarian Rhapsodies. It really helps to hear how something can be played five different ways, yet still sound good each way.
