Metheny:

But when Kenny G decided that it was appropriate for him to defile the music of [Louis Armstrong] by spewing his lame-ass…playing all over one of the great Louis’s tracks…he did something that I would not have imagined possible. He, in one move, through his unbelievably pretentious and calloused musical decision to embark on this most cynical of musical paths, shit all over the graves of all the musicians past and present who have … developed their own music inspired by the standards of grace that Louis Armstrong brought to every single note he played over an amazing lifetime as a musician. By disrespecting Louis, his legacy and by default, everyone who has ever tried to do something positive with improvised music and what it can be, Kenny G has created a new low point in modern culture - something that we all should be totally embarrassed about - and afraid of. We ignore this, “let it slide”, at our own peril.

It happens in every industry.
