Julian Cannonball Adderley : While a knack for interpreting funky crossover material such as Zawinul’s Mercy, Mercy, Mercy won the Adderley quintet one of the jazz world’s largest audiences, Cannonball’s personality also played a pivotal role in sustaining the band’s prominence among fans worldwide.
@allmusic : One of the great alto saxophonists, Adderley had an exuberant and happy sound that communicated immediately to listeners. His intelligent presentation of his music (often explaining what he and his musicians were going to play) helped make him one of the most popular of all jazzmen.
@last.fm : He was also a high school band director at Dillard High School in Ft. Lauderdale, Florida for some years. The name ‘Canonball’ is supposed to have originated from his being nicknamed ‘cannibal’ in his youth, on account of his prodigious eating.
