Special Episode! Oscar-winning director Damien Chazelle sits down with his composer Justin Hurwitz ahead of their new film, BABYLON. Why Chazelle involves his composer long before his script is "final," and how he uses it to create storyboards. How the music of WHIPLASH and LA LA LAND were informed by music, and the challenges of bringing to life the 1920s-era BABYLON with all its brilliant, raucous and cacophonous musical splendor. Interview by Robert Kraft and Matt Schrader.
