Improvising on Bach? Yes, why not? What I do here is take the first prelude in his Well-Tempered Clavier and play what is meant to be played in two hands in my left hand. Then, I improvise over it in my right.

This comes from my album - Blues, Preludes, Feuds: https://songwhip.com/petersaltzman/blues-preludes-and-feuds-14

There are three other examples on that album of me messing with Bach.

Long story short: everything from solo piano to pop to orchestral film.  I wish I could focus on one thing but can't because I'm a MUSICIAN.
