When I was young (and still somewhat green) I had the very good fortune to have master jazz pianist Hal Galper play with me on my first album. I soon realized that I still had a lot to learn and a few years later I took some private lessons with Hal which completely changed the way I thought about music. This video is a must watch for anybody who is interested in playing jazz (or any other style of music).
Hal is one of the premier jazz educators of our time. I encourage you to visit his site: http://www.halgalper.com/
