The Mother of Us All

The Mother of Us All is a two-act opera composed by Virgil Thomson to a libretto by Gertrude Stein. Thomson and Stein met in 1945 to begin the writing process, almost twenty years after their first collaborative project, the opera Four Saints in Three Acts. Stein wrote the libretto in the winter of 1945–46 before sending it to Thomson in March. After Stein's death in July, Thomson began working on the score, which he finished within just a few months.
