It is not to say there are not other extremely gifted and great musicians out there. But, the thread was titled OP, so thought that was the main focus. This is a beautiful piece you have posted by Keith Jarrett, a musician I was not familiar with. But, more so now. So, thanks for posting it.
This is quite different then what I would expect from Mr. P., though. For one thing, it doesn't swing. Nor is it supposed to, I suppose. So, it is just WAY different.
Peterson certainly was not the most accurate/precise piano player I have ever heard. There are much better if this were the criteria. But, hard to beat when it comes to a really swinging sound. Just like when Ella Fitzgerald gets passed the MIC from Barbara Streisand, the chandeliers start to swing. Both are extremely gifted singers (IMHO,) but WAY different.
