Keith Jarrett is a jerk?
No. Who came up with that search term? Keith Jarrett is a jazz pianist who has performed with legends like Miles Davis. His musical talents were apparent when he was very young. He had absolute pitch, and started piano lessons at age three. He gave his first formal recital at age seven. He is known for his frequent, loud vocalizations and strange gyrations while performing.
