It's certainly no coincidence that big bands became the entertainment of the army in WWI and WWII, and that jazz drumming style is very military influenced. The snare drum comes from the military and becomes the core kind of sound of jazz drums.

When someone is playing drums, they aren't actually moving around a space; they're just moving their arms and limbs. They're stuck behind the drum set. So to film someone playing the drums and make it feel as kinetic as a car chase or a shootout or a battle scene was the challenge.

Certainly, my manager Gary Ungar was the first person to give me any attention and hustle for me. This was back in 2009.

It's easy to show terrible people's behavior on screen, and we all just kind of nod and go, 'Isn't that terrible.' It's more interesting when you can show terrible behavior in the interest of something good.
