An Entertainment in 2 Acts. Transformations was originally published as a book of poems by Anne Sexton in 1971. Her story-poems recreate, with wit and unsettling humor, 17 familiar tales (from The Brothers Grimm) and, with relentless honesty, uncover her own personal demons. With the author’s cooperation, nine of these poems were taken verbatim and set as a contemporary opera by Conrad Susa.
