Nevertheless, this is one of the best and most overlooked of the Cannonball Adderley Capitols, a rumbling session that bursts with the joy of working in an unfamiliar yet vital rhythmic context. Cannonball turns in one of his swinging-est solos through a Varitone electronic attachment on Caiphus Semenya's "Gumba Gumba" and "Marabi" is a real hip-jiggler; you can't sit still through it. Other highlights include Cannon preaching blue smoke in his own Afro-Cuban-blues-flavored "Hamba Nami," a dignified trip through Wes Montgomery's "Up and At It," and Nat Adderley's commanding work on cornet at all times.
