One of the original members of the indie band Arcade Fire, Richard Reed Parry (THE IRON CLAW, EILEEN) discusses his jump into film scoring, the importance of finding “mojo” and “vibe,” and how the wrestling biopic The Iron Claw nearly stumped him musically — until he unlocked the rich, layered sound that carries the film. How Spike Jonze’s film “Her” prepared him for the next stage in his career, and why he believes it’s important to be as musically dynamic with other musicians as possible.
