Here’s a basic sketch of Monty Alexander’s “Renewal”. True to its title, I don’t think he ever plays it the same way twice. I’ve heard about half a dozen versions of the tune in different styles and tempos. One of my favorites can be found on the album Threesome, with Niels-Henning Ørsted Pedersen and Grady Tate. On that record they give the head a long rubato treatment before easing into a swinging reggae feel.
