After working out both hands practicing technique, it would be interesting to work on dynamics. However, apart from the advice to "play with others" I have not really seen a more concrete pointer. The book Jazz Workshop is good and I'm wondering if there are other books that address dynamics specifically when playing drums.
I'm aware of the exercises where one can adjust the volume of one specific limb or a drum but I'm wondering if there is more theory available on when/how to play soft or hard, etc. This may go into composition, arrangements, and orchestration, and it would be ok to address these topics at the same time.
