A Master Class in Playing Jazz with Pianist Kenny Werner
This is really good:
In this clip from http://www.artistshousemusic.org – Jazz Piano great Kenny Werner conducts a master class in jazz piano at the famed Blue Note in New York. He addresses a wide variety of issues that jazz players on all instruments face – issues of confidence and mental preparation, techniques for better improvisation and for improving your ability to collaborate, and how to overcome the mind games that every musician plays with themselves over "what to play next?" and "does this sound good?" He also demonstrates his approach to music with several performances of standards and original compositions.
