Query: Inaudible sound

This is an excellent performance. Not in the baroque/authentic vein of more recent interpretations like Harnoncourt's or Gardiner's, but that makes it all the more vital and alive. The sound however of this particular issue is so bad that it is impossible to listen to. This reviewer is used to sound from the first decade of the 20th century, so when I say bad, I mean really bad, and this is not an inherent fault of the source recording but purely a blunder in the mastering.
