urning the Key provides more than a compelling juxtaposition of Haydn and Beethoven. It demonstrates how wit, faith, fear, and hope coexist within a single musical tradition. Thomas Crawford, the American Classical Orchestra, its chorus, and four distinguished soloists restore the music’s human scale while preserving its sublimity. The ACO’s ongoing Beethoven cycle offers performances that let familiar masterpieces engage, challenge, and console listeners, ultimately revealing new interpretive possibilities.
