BTW amazon.com now lists the Nimbus CD Don Satz mentioned- apparently
quartets 1 (in c minor, op.  20, afaik) and 5 are on it.  (I have a slight
financial connection with amazon.com, in that I maintain a website that is
an amazon.com associate, and I should mention that upfront as it would be
rather slimy of me not to...)
