Within days of Charlie "Bird" Parker's death at the age of thirty-four, a scrawled legend began appearing on walls around New York City: "Bird Lives." Gone was one of the most outstanding jazz musicians of any era, the troubled genius who brought modernism to jazz and became a defining cultural force for musicians, writers, and artists of every stripe. Arguably the most significant musician in the country at the time of his death, Parker set the standard many musicians strove to reach--though he never enjoyed the same popular success that greeted many of his imitators. Today, the power of Parker's inventions resonates undiminished; and his influence continues to expand.
