Simonsen’s ascent as a film composer began when his score for indie film Westender caught the attention of composer Mychael Danna. Through subsequent collaborations with Danna, Simonsen contributed additional music to features Moneyball and Life of Pi, and co-composed the score for 500 Hundred Days of Summer. As a result, Simonsen received attention towards his own scores, prompting The Hollywood Reporter to list him as one of the “Composers primed to take their place on the A-list”.
Fulfilling this prediction, Simonsen has collaborated with directors Shawn Levy (The Adam Project), Jason Reitman (Ghostbusters: Afterlife and The Front Runner), Julia Hart (Hollywood Stargirl, Stargirl and Fast Color), Greg Berlanti (Love, Simon), Gavin O’Connor (The Way Back), Bennett Miller (Foxcatcher), Marc Webb (The Only Living Boy in New York, Gifted, and 500 Days of Summer), and Henry Joost and Ariel Schulman (Viral and Nerve). His music has been called “perfectly calibrated” by the New York Times, “Sensitive” and “Sophisticated” by Variety, and “rich” by Hollywood Reporter.
Simonsen’s dedication to artistic expression extends beyond film work. Surrounding himself with a network of dedicated artists, he co-founded The Echo Society to connect and inspire the Los Angeles community with live and interactive audiovisual performances.
Upcoming for Simonsen is The Whale for A24, directed by Darren Aronofsky, slated for release in 2022.
