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?). Ron Chaplin
