Query: Excellent recording by an excellent orchestra

The San Francisco Symphony is an excellent Mahler and Strauss orchestra. The blend and ensemble skills are really great in this recording. The basses sound nice and fat in the first movement, the brass really has some power, and it's just a great interpretation by a great conductor from a great orchestra. They really bring out the col legno section in the first movement well - great effect. This and Seiji Ozawa's BSO recordings are my two favorites for this piece.
