Recently I seem to have been hearing an awful lot of recordings of legendary pianists who get into trouble when they try to play too fast. I won't name names, but I could easily furnish a dozen examples, male and female

Most of the time, but not always, it's a recording of a live performance.
What usually happens is -- they're playing along, giving a dazzling performance, and all of a sudden they hit the hard part, or they do an accelerando, and it all falls apart -- sometimes a little bit, sometimes a lot. Maybe they don't literally make mistakes, but their playing loses its musical quality. The notes are there, but they're uneven, or not phrased, or the right hand is OK but the left hand turns to crap.
Am I being too picky? Should I cherish these recordings for their magical moments and ignore the not-so-magical ones? Has anybody else noticed this phenomenon?
Should I name names?
