Rom, the idea is that he could hear the stick break on the recording but the CD seller could not. The guy thought the disc was bad, or something. He couldn’t figure it out so he went to a live performance to hear an unabated version of the performance. At the performance with front row seats, he discovered that the end of the piece has the conductor breaking his stick, as the piece was intended. He was relieved to find out he was suppose to hear it, and simply others couldn’t presumably because they don’t have an absurd CDP.
