You are more purist than some jazz musician going back to Africa to study drum tradition and trying to understand when ANY music "roll" or not...
i dont remember his name...
A music "roll" when his tempo is not external to the melody but emerge and "roll" inside it not with it or beside it...
Then "non sense" is not the right qualitative word for my remark and my post...
Anyway it is not "pure" jazz...
Happy Easter
but somewhere it is in the tree of jazz roots nonsense
