If I were to run around the world playing just the cello concertos - and believe me, I love playing them - I would be counting my entire repertoire from year to year on my two hands.

The zenith of virtuosity, a violinist like Jascha Heifetz, the supernatural in a pianist like Vladimir Horowitz, these are performers who were so idiosyncratic and personal that to imitate them would be like filling somebody else's bottle with your wine.

Being an artist and a musician, I have witnessed the previous generation taking the art form, not as a way of making a living, but as a belief, an almost maniacal, sometimes insane devotion and commitment to communication.

I would say that for the younger musicians, technical proficiency is necessary and a given these days. But the study and the way you function in society, your beliefs and the way you live, that is where you will find a real musician, a real artist.

A lot of my musical education was done simply by listening. If you really want to excel on your instrument, it's almost impossible to not develop and analyze what you see and hear and to incorporate all of it into your own playing.

When I finally got together with Rostropovich as a student, he was very focused, almost entirely focused on the music itself, on what the composer had in mind and what he knew about the composer. Many of the works that I played for him had in fact been composed and written for him; he was often the first performer of these works, having known the composers personally.

Beginning in the nineteenth century, with performers like Franz Liszt, were musicians who were able to excite an audience and communicate on a whole new level.
