One of the hardest to find is the Richter in Leipzig recital which I noticed was selling second hand on Amazon for $999.00. Music and Arts could put an end to this by simply reissuing the recording.
Yes, you'd think that with all of these reissues of items that were already in print, the labels would have the time and sense to do so.
I'm guessing the smallish label M&A is like Pearl, in that things that come out don't stay out for long and then don't re-appear?
Perhaps one day we'll see it on Archipel or Brilliant?
