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.

The first thing I did as a child was draw. I wanted to make animated movies. I think Disney's 'Cinderella' was the first movie I ever saw. 'Peter Pan' was the first movie I ever saw in the movie theater. I grew up with 'Dumbo' and 'Pinocchio' and 'Sword in the Stone.' Those were the movies I wanted to make.

I remember moving out to L.A. straight after college and just starting to try to write scripts and trying to get stuff off the ground.

I do truly believe that the smallest stories can wind up being the biggest because it's through the specific that a writer can best access the universal.

I had seen a lot of music movies that celebrated music or that showed the kind of joys from playing music, which is a big part of it of course, and not something that I would want to deny.

What I love about jazz is that it's full of legends, full of myths. It's an oral history because it started in New Orleans and Kansas City, under the radar.

There's something about some of my favorite musicals that they put me in a sort of heightened state where I feel like I'm floating out of the theater rather than walking out.

I didn't feel the kind of joy every day playing drums that I thought you were supposed to feel.

I remember when I first met Jason Reitman with the 'Whiplash' script; he quickly became a mentor figure who guided me through the process and also protected me and made sure that when it came time to actually make 'Whiplash,' I was able to make exactly the movie I wanted to make.

I wanted to look at the mentality that can breed that sort of intensity, that kind of cutthroat, pressure-cooker feeling, especially a form of music like jazz, that should be - or you'd think should be - all about liberation and improvisation and everything.

I would break a lot of cymbals. You whack the cymbals hard enough, and they will crack in half. Drums are not actually as sturdy as they look. They're actually somewhat fragile instruments.

When you're trying to paint a portrait of a very specific world, you're trying to show what makes the world different. So, sometimes it means exaggerating certain kind of aspects, but I don't think it's that important or it's that much of an issue as long as you get an emotional truth across.

I think, especially living in L.A., it's very easy to get wrapped up in weekend announcements and the trades and the whole social life of the city, and to get divorced from what actually matters.

The greatest thing has been that projects that were pipe dreams before 'Whiplash' are now feeling more realistic.

It's a little difficult when something goes from being an utter obsession - a thing where your skill defines you as a person - to it just being a thing you occasionally do.

I don't think of 'Macbeth' as the villain. I don't think of 'King Lear' as the villain. I don't think of 'Hamlet' as the villain. I don't think of 'Travis Bickle' as the villain.

I'm predisposed to never be in pure celebration mode.

If there's a good review, I'll skip over the headline, but I always find the bad reviews and read those. I don't know why. It's a little sick and demented.

I was always pretty decent at fast stick work or doing stuff that seems impressive that's not really; I was pretty tasteful and had good ideas musically. But I had a terrible sense of tempo, which is like being a blind painter. The conductor would just rip into me, and it lasted for years.

At the upper echelon of musicians in general, I guess performers in general, you have to have this kind of live-or-die, cutthroat mentality.

Certainly, grades only matter so much when you're in Hollywood. But I became an utterly motivated, devoted, committed student. I was a good student because I was convinced that it would somehow help me in my quest to become a filmmaker.

By the end of high school, I had this fork-in-the-road moment where part of me considered going to vocational music school to really pursue it.

It's interesting when you wind up distilling all your ambitions and your goals and dreams into one single person. It's giving that person a lot of power.

My version of a stress dream is, really, showing up on a concert stage with a drum set and not knowing the chart.

I guess art itself is insane. Its actual function is rarely clear, and yet people give their hearts and souls and lives to it, and have for all of history.

There are no large-scale original musicals being made right now. They're all Broadway adaptations and jukebox musicals or catalog musicals, and they just don't interest me as much.

The go-to reflex all over Hollywood is still likeability. I've always had a problem with it because I think I have a weird barometer in the sense that some of the characters I've cared about the most in movies are characters that are often thought of as despicable.

There are a lot of musicians in my life. But movies came first for me. That was my original passion.

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.

There were so many specific things from high school jazz band that I remembered: the conductor searching out people who were out of tune, or stopping and starting me for hours in front of the band as they watched.

If you look at 'West Side Story,' a lot of those numbers are actually pretty cutty, but the cuts are always musically motivated.
