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.
Her death was announced by her brother David Wooldridge.
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, including one with Sidney Poitier.
Long recognized as one of jazz's most arresting and uncompromising singers, Ms. Lincoln gained similar stature as a songwriter only over the last two decades. Her songs, rich in metaphor and philosophical reflection, provide the substance of Abbey Sings Abbey," an album released on Verve in 2007. As a body of work, the songs formed the basis of a three-concert retrospective presented by Jazz at Lincoln Center in 2002.
