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.
