For a while now, my favorite cellist has been Boris Pergamenschikow. I had been going through all the Bach on the Naxos Server and hating it all, and then I got to his, and, well, it was pretty much perfect.

Earlier this evening, I thought I had found it on youtube, but it turned out to be Mischa Maisky. Who is also awesome, and whose Bach I like almost as much.
Here's the fifth suite:

( Bach V )

And here's Boris Pergamenschikow giving a Master Class on the Shostakovich concerto. Oh, I wish I could have studied with him!
