From the outset of his Tenth Symphony it is clear that Mahler was tentatively entering into a new sonic realm of expanded chromaticism and rhythmic freedom, tragically cut short by his untimely death. For the most part the Orchestre Métropolitain delivers a mostly impressive performance. Nézet-Séguin brings forth a beautifully veiled pianissimo behind the exquisite flute solo in the moving finale of the work. Nézet-Séguin clearly has something special to say about this least familiar Mahler symphony, and I am willing to forgive its relatively minor shortcomings.
