This is just a short one, shot on somebody's iPhone (probably!), but I was fascinated by John's explanation of how he uses different inversions of double strokes between the snare and bass drum while playing time with the ride cymbal to develop further vocabulary for comping:
I like his ideas of dealing with permutations of the double strokes, varying the speed (eighth notes to triplets) and then also leaving notes out. It's a simple enough concept but combined with some imagination and creativity those patterns should give one enough ideas to develop over a lifetime!
