Hi, my name is David Whitbeck. I just joined this list. I tried out another classical music list before (the Mahler list) because I listen to Mahler more than any other composer. I decided that I wish to seek out a broader discussion of music. I found a newsgroup that looked quite good. But I don't like feeling so exposed to the merciless spam-bots. So now I'm here. Now for my question: On these two recordings that I have (Beethoven Piano Concertos Nos 3,5 Royal Edition Sony Classical Bernstein New York Philharmonic, Mozart Piano Concertos Nos 21,27 DG Abbado London Symphony Orchestra) with Serkin on the piano on both recordings; I occasionally here this odd sound. Have you ever heard the weird moaning sound of wind when you're inside close to a window? Well I hear something like it on these recordings: a moaning wind sound. Can anybody tell me what that sound is? David Whitbeck
