Having been raised in a musical family, Rob Simonsen gravitated towards the piano at an early age. When he was 14, his dad gave him an old Mac SE with a very basic midi programme and he started sequencing, and kept doing that ever since.
After having played in a number of jazz fusion bands, Simonsen began scoring films for friends and later contributed additional music to a number of big film scores, including the score for Life of Pi, which won an Academy Award for Best Original Score. In 2008, Simonsen co-scored 500 Days of Summer with Mychael Danna, which kicked off his career as a film composer. Since then, he has signed with Kraft-Engel and scored numerous films, such as Foxcatcher (2014), Nerve (2016) and The Spectacular Now (2013).
An avid collaborator, Simonsen founded Los Angeles-based artist collective Echo Society in 2013. The collective seeks to create connections within the Los Angeles arts community, while bringing both orchestral and electronic music to new audiences.
