Klaus Tennstedt's BSO Mahler 4th has become available from Parnassus for
$50.  I can't afford it, but I heartily recommend it for those who can.

For a few years Tennstedt and the BSO had a truly special relationship,
and nowhere was this more evident that at this concert.  It ranks among the
greatest Mahler the BSO and Tennstedt ever gave us.  One also remembers the
Mahler 2nd with Abbado, the Das Knaben with Colin Davis, and the Das Lied
and 3rd with Levine.
