A dazzling Mozart motet, the world premiere of a new piece by a daring American master, and Mahler’s radiant Symphony No. 4 are featured. Mozart’s Exsultate, Jubilate is wonderfully exuberant and culminates in spectacular coloratura fireworks that are ideally suited to the “silky, flexible sound” (The New York Times) of soprano Pretty Yende. She also sings the child’s praise of heavenly joys in the finale of Mahler’s Symphony No. 4, a work that glows with a sense of wonder and magic.
