Thomas and Rawhide, I agree with both you. I'm not a big Kenny G fan, but I appreciate that he has captured a sound that appeals to many, and he obviously has a level of skill that is worthy of respect, despite the venom Pat has developed in response. I must admit I am not a Pat Metheny fan either, though I respect his skill.And while I understand the sentiment Peter T expresses, it is not one I share. The lovely piece Natilie did with her father's music was gift - a technology created "artificial insemination" (if you'll forgive the analogy) across genereations. I am certain that Nat would not only be proud of his daughter's effort, but would be pleased with the result. She did not change the original. She added a new thought to the old, and created a whole new piece.
Andy Warhol and many other artists purposely build new pieces on top of old ones nad come up with new and interesting pices, some of which are well worthwhile in their own right. I believe Natilie's effort was such a piece. I am not so sure about the others mentioned (Kenny G's and Tony Bennett's). I haven't heard them, and would shy away from doing such a thing myself, ordinarily.
