I'm listening to Nielsen: String Quartets Vol.  1 on Naxos, 8.554907.
In the first three movements of the E flat major, I am noticing a buzzing
sound from time to time.  Has anyone else heard this? Is my Discman on it's
last legs? Is it part of the recording? It doesn't appear that the disc is
defective.  Could it be that one of the members of the Oslo is expressing
himself vocally, the way Lionel Hampdon (SP) does (did?).
