Found this delicious version of Bach's Chaconne tonight. Although this piece was written for solo violin, believe it or not, it stands up well when transcribed for piano. This is probably the best piano version I have ever heard. Simply beautiful. 

The great violinist Jascha Heifetz said of this piece, "I have played it for 50 years and I still don't understand it." That's Bach. You can listen to his music over and over, played by different people on different instruments, and you still won't reach the bottom of the well. 

Here is Heifetz, in total command, as usual.
