It was premiered by the New York City Opera in 1949 and became the first opera written by an African-American to be performed by a major American company. The libretto was largely written by the poet Langston Hughes and the score by the dean of African-American composers, William Grant Still. In the interest of full disclosure, Still was also my grandfather.
