To Wes Crones recommendations, I add The Keller Quartet (ECI) - which I prefer to the Juilliard The Arrangement for orchestra by Hermann Scherchen. I think that he made more than one recording and I don't recall the details of the one I obtained a year ago from Berkshire,, but it is wonderful. And the fact that is orchestral should not mislead you- no mass effects!!! It is still chamber music. Professor Bernard Chasan Physics Department, Boston University
