When working on these loops, try to get references from records in this style: listen to the drummer but also to the entire group. Do not reduce your vision, music is a whole, and the only way to understand any style is with thorough analysis. Most modern musical styles descend from jazz. This style is the main source of multitude of styles. Just listen to the big bands of the fifties (Duke Ellington, Count Basie, Benny Goodman,…) and go on to listen to the evolution of this great style (Bebop, Mainstream, Hard Bop,…) In this case, the swing rhythm is introduced with a 3/4. Some jazz standards use this kind of pattern (jazz-waltz).
