I got the Koussevitzky today. I love it!! I have been playing through it (first movement) all day (and I will again tomorrow and the day after). It is one of the most beautiful pieces ever written. I think it is even up there with the Bottesini Concerto's. I have heard allot of recordings and as I looked over my music allot of people don't maintain tempo and turn 8ths into triplets and speed up at the ritards. Is this common practice for it? I plan to play it as written but I'm open to interpretation ideas. I would like to say again this isn't the hardest thing in the world but it is definitely one of the best.
