Playwrights Horizons presents the world premiere of Doris to Darlene, A Cautionary Valentine, a new play by Jordan Harrison, directed by Les Waters. In the candy-colored 1960s, a biracial schoolgirl named Doris is molded into pop star Darlene by a whiz-kid record producer who culls a top-ten hit out of Richard Wagner's Liebestod. Rewind to the candy-colored 1860s, where Wagner is writing the melody that will become Darlene's hit song. Fast-forward to the not-so-candy-colored present, where a teenager obsesses over Darlene's music -- and his music teacher. Three dissonant decades merge into an unlikely harmony in this time-jumping pop fairy tale about the dreams and disasters behind one transcendent song.
