Guettel’s tunes are richly textured and warmly atmospheric; like the Tuscan light of Spencer’s story, they create “the sense that everything is clear and visible, that nothing is withheld.” [...] Guettel’s music and lyrics take nothing from the razzle-dazzle bargain basement of feeling; they represent, instead, a genuine expense of spirit.

The theater composer Adam Guettel is so overwhelmingly gifted that any news of his activities stirs the kind of fervent expectations that surround Stephen Sondheim, and before that, Leonard Bernstein.

But the music [...] is steadily absorbing, even if only intermittently melodious. One duet, “Let’s Walk,” is an unqualified hit, but the rest, without fully cohering, is also arresting. It is—to offer a classical parallel—as if a world weaned on Brahms were suddenly confronted with Schoenberg.
