One interesting thing about jazz, or art in general, but jazz especially is such an individual art form in the sense that improvisation is such a big part of it, so it feels like it should be less soldiers in an army and more like free spirits melding. And yet, big band jazz has a real military side to it.
In some ways, jazz is the most precise of art forms and the loosest in the sense that it's all about improvisation, but the musicianship required is kind of insane. To actually play with real jazz musicians is a different level of musicianship that almost has no equal in any other form of music in the world.
I didn't have traditional stage fright. If there was 500 people in the audience or three people in the audience, it didn't really make a difference. What made a difference was the conductor. Everything that I was scared about as a drummer was him. It was his face. It was whether or not he'd approve of my playing.
Whiplash' was just a lucky kind of convergence of events in that I'd been trying to get a bigger project off the ground with no success for a while, and then finally, out of frustration, I just wrote this leaner, meaner, personal script about my experiences as a jazz drummer, and that's the one that wound up getting made.
There's something very particular about the kind of rage you feel when you're alone in a practice room by yourself, unable to master a simple thing like a rudiment. You keep trying to master this very basic thing, and when you don't get it, you just scream. I broke a lot of drum heads, and I broke a lot of sticks.
