Duke Ellington called his music "American Music" rather than jazz, and liked to describe those who impressed him as "beyond category." He remains one of the most influential figures in jazz, if not in all American music and is widely considered as one of the twentieth century's best known African American personalities. As both a composer and a band leader, Ellington's reputation has increased since his death, with thematic a re-packagings of his signature music often becoming best-sellers. Posthumous recognition of his work include a special award citation from the Pulitzer Prize Board.
