Mulgrew Miller was an American jazz pianist, composer, and educator. As a child he played in churches and was influenced on piano by Ramsey Lewis and then Oscar Peterson. Aspects of their styles remained in his playing, but he added the greater harmonic freedom of McCoy Tyner and others in developing as a hard bop player and then in creating his own style, which influenced others from the 1980s on.

Betty Carter was an American jazz singer known for her improvisational technique, scatting and other complex musical abilities that demonstrated her vocal talent and imaginative interpretation of lyrics and melodies. Vocalist Carmen McRae once remarked: "There's really only one jazz singer—only one: Betty Carter."
