Pianist, composer, and bandleader Keith Jarrett is one of the most prolific, innovative, and iconoclastic musicians to emerge from the late 20th century. As a pianist (though it is by no means the only instrument he plays) he literally changed the conversation in jazz by introducing an entirely new aesthetic regarding solo improvisation in concert. Though capable of playing in a wide variety of styles, Jarrett is deeply grounded in the jazz tradition. He has recorded nearly 80 albums as a leader in jazz and classical music. And he has won the Down Beat Critics Poll as a pianist numerous times -- including consecutively between 2001 and 2008.
