I've been listening to Mahler since the early 60's. Probably heard just about every recording of every work over the years. My taste is Bernstein, not Abbado, Haitink and definitely not Rattle. This recording with Boulez and superb singers, soloists and musicians is beautifully filmed and the accoustic excellence is first class. I think that the architecture, phrasing, dynamics and overall concept are all beyond praise. Barenboim can be glimpsed in the audience. For me, this is the best realisation of a Mahler symphony I could ever have hoped for. Praise indeed! But that's my opinion. Try it for yourself.
