Rob Simonsen is a composer, solo artist, and co-founder of the composer collective, The Echo Society.

His musical journey began as a boy, when he started to experiment on the piano by ear. Encouraged by his grandmother, a music director and vocal teacher, he began to take piano lessons, and eventually pursued studies in jazz piano and music throughout college.

Simonsen's professional journey began when his score for the indie film Westender caught the attention of renowned composer Mychael Danna. His early work included contributing additional music on films like Moneyball and Life of Pi, as well as co-composing the score for (500) Days of Summer.

Film composition has been a prime focus of Simonsen’s career. He has collaborated with esteemed directors such as Darren Aronofsky (The Whale), Shawn Levy (The Adam Project), Jason Reitman (Ghostbusters: Afterlife, Tully), The Duffer Bros (Stranger Things), Greg Berlanti (Love, Simon), Gavin O’Connor (The Way Back), Bennett Miller (Foxcatcher), Julia Hart (Stargirl, Fast Color), Marc Webb (500 Days of Summer, Gifted), and Henry Joost and Ariel Schulman (Nerve). His scores have drawn praise from publications including the New York Times, which described his compositions as “perfectly calibrated,” as well as Variety and the Hollywood reporter.

His compositions have also been used in advertisements for brands including Apple, Nike, Coca-Cola, AT&T, EA Sports, Toyota, Subaru and more.

In 2013, Simonsen co-founded The Echo Society to bring together a network of like-minded artists looking to connect and inspire the Los Angeles community with enriching site-specific live and interactive audiovisual performances.

In 2019, Simonsen released his solo album "Reveries" on Sony Masterworks (can you say something about the music).

As he continues his career, Simonsen remains dedicated to exploring the profound impact of music on mind and heart, seeking to illuminate the human experience through the transformative power of sound.
