Transformations is a chamber opera in two acts by the American composer Conrad Susa with a libretto of ten poems by Anne Sexton from her 1971 book Transformations, a collection of confessional poetry based on stories by the Brothers Grimm. Commissioned by Minnesota Opera, the work, which is described by its composer as "An Entertainment in 2 Acts", had its world premiere on 5 May 1973 at the Cedar Village Theater in Minneapolis, Minnesota. Anne Sexton, who had worked closely with Susa on the libretto, was in the audience. It went on to become one of the most frequently performed operas by an American composer with its chamber opera format of eight singers and an instrumental ensemble of eight musicians making it particularly popular with smaller opera companies and conservatories. The 2006 revival production of Transformations at the Wexford Opera Festival won the Irish Times Theatre Award for Best Opera Production. Background and performance history Transformations was commissioned from Conrad Susa in 1972 by Minnesota Opera, a company specializing in new works by American composers. Later that year, Susa approached the American poet Anne Sexton with the idea of using her 1971 book, Transformations, a poetic re-telling of sixteen stories by the Brothers Grimm, as the basis for the libretto. Delighted with the idea of hearing her poetry as song, she cooperated closely with Susa in selecting and arranging the ten poems which would form the basis of the opera. Transformations premiered on 5 May 1973 at the Cedar Village Theater in Minneapolis, Minnesota. The premiere production was conducted by Philip Brunelle and directed by H. Wesley Balk with set and costume design by Robert Israel and lighting design by Bruce Miller. Sexton herself was in the audience that night. She subsequently returned to Minneapolis for further performances and made a tape-recording of the opera which she listened to repeatedly and played for her friends and family. In August 1978, the opera received its US television premiere when it was broadcast on the PBS network in a slightly shortened version performed by Minnesota Opera and co-produced by WNET and KTCA. Anne Sexton did not live to see the broadcast. Throughout her life she had suffered from mental illness with repeated suicide attempts followed by stays in psychiatric hospitals. On 4 October 1974, dressed in her mother's old fur coat, she killed herself at her home in Weston, Massachusetts. Transformations went
