If Charlie Parker was the chief architect of the bop revolution of the 1940s, Dizzy Gillespie was its standard-bearer, an evangelist who battled public hostility and incomprehension with rapier wit. A trumpeter of dazzling virtuosity, he matched Parker's rhythmic innovations with deft harmonic ingenuity. He also functioned as teacher, putting his vast knowledge of harmony at the disposal of younger musicians like Miles Davis, who were trying to get a handle on the new sound. His historic big band featuring Chano Pozo was the first large-scale attempt to combine Latin music with jazz, and the unflagging excellence of his subsequent career was a tribute to the integrity of his original vision. He died in 1993.
