Pulitzer Prize-winning composer Shulamit Ran was in residence at Marlboro in 2018 and worked extensively on her own music with the musicians in Vermont. Alternating between contemplation and ecstasy, Ran’s Moon Songs for soprano, flute, cello, and piano are at the center of this program, which also includes Mozart’s substantial Divertimento and Haydn’s charming String Trio Op. 53, No. 1.
