This is a video of cellist Sol Gabetta explaining the Dvorak Cello Concerto...unfortunately it's in German, but she is absolutely stunning! It's really interesting if you can understand the basics of what she is saying.  She really understands this piece and explains the importance of the interaction between her and the other instrumentalists.  I'm fascinated by her playing and really wish she would come to the United States again.  She teaches at the Basel academy in Switzerland.
