I feel very sad hearing this news. I have loved JR's playing since the 60's and, like many others, have spent countless hours trying to play his tunes. I have seen him quite a few times going way back. His compositions and arrangements were so musical and ingenious. There was some unique and undefinable atmosphere in his tunes that really appealed to me. In his prime he had an incredibly deft and accurate technique which no one could copy. In my book he was unmatched.
