The long-awaited first collaboration between two icons, Count Basie and Frank Sinatra, did something unique for the reputations of both. For Basie, the Sinatra connection inaugurated a period in the '60s where his band was more popular and better-known than it ever was, even in the big-band era. For Sinatra, Basie meant liberation, producing perhaps the loosest, rhythmically free singing of his career. Propelled by the irresistible drums of Sonny Payne, Sinatra careens up to and around the tunes, reacting jauntily to the beat and encouraging Payne to swing even harder, which was exactly the way to interact with the Basie rhythm machine – using his exquisite timing flawlessly.
