The outstanding American mezzo Susan Graham joins Andris Nelsons, the BSO, and the women of the Tanglewood Festival Chorus for Mahler's Third Symphony, which, along with his Symphony No. 2, exemplifies the composer's ambitious expansion of the symphonic genre. This is the second of Mahler's trio of "Wunderhorn" symphonies (Nos. 2-4) employing text from the folk-poetry collection "Des Knaben Wunderhorn". The six-movement symphony is divided into two parts. Part I is a massive, 30-plus-minute opening movement representing a Bacchic procession celebrating the arrival of summer. Part II (movements 2 through 6) is a series of character pieces representing the responses of, in turn, wild flowers, animals of the forest, mankind itself, angels, and the spirit of love. Produced by Anthony Princiotti.
