I think it is tragic that such an excellent intstrumental performance should be marred by some very unpleasant vocalizing.I can't understand why so many fans take it for granted. I would rate Keith Jarrett very high as a pianist; in the same league as Herbie Hancock and Chick Corea; if only he could keep his mouth shut while he plays his pianistic miracle.
