You are quite right. The bootleg floating around that is being made available from Honduras is abysmal and does no justice to the original recording that SMR use to play at his workshops. This is exactly why he and his family have always been wary about lending them out before they could be properly produced. None of the recordings of SMR offered by Mr. Kendall are properly produced and I can't help but question his motives. Also those people to whom Mr. Rascher entrusted with copies from his private library should be ashamed of themselves for distributing these recordings so recklessly and against Mr. Rascher's wishes. What Mr. Kendall is doing now is just the thing SMR and his family feared would happen.
There's a much better master of that Univ. of Colorado performance and with any luck, one day a responsible individual will be found who will treat these masters with the respect that they deserve.
