Abbey Lincoln, a singer whose dramatic vocal command and tersely poetic songs made her a singular figure in jazz, died on Saturday in Manhattan. She was 80 and lived on the Upper West Side. Ms. Lincoln’s career encompassed outspoken civil rights advocacy in the 1960s and fearless introspection in more recent years, and for a time in the 1960s she acted in films with Sidney Poitier. She was married to Jazz icon Max Roach from 1962 to 1970. Her singing style was unique, a combined result of bold projection and expressive restraint. Because of her ability to inhabit the emotional dimensions of a song, she was often likened to Billie Holiday, her chief influence. But Ms. Lincoln had a deeper register and a darker tone, and her way with phrasing was more declarative. - New York Times
