Elliot Callighan

CEO | Composition

He began playing piano at eight, guitar at 12 and at 20, Daft Punk convinced him to give the computer a shot, too. (thankfully!)


To pursue music and audio, Elliot enlisted in the Army National Guard. This path led to degrees in Music Composition and Sound Design, a commission as a Military Officer, and his work being featured in campaigns for United Airlines, Instagram, Spiderman: Far From Home, GMC, The Godrej Group, Chevrolet Motors, the Goodman Theatre and the Joffrey Ballet as well as many films and games.


Elliot always focuses on creating distinct personality and aesthetic in all audio while maintaining that memorable "hummable" factor in his music. He brings this sensibility to his work in games, film, trailer and commercial projects. He has served as Soundpost Co-Chair for the Chicago Symphony Orchestra Overture Council and teaches as Adjunct Faculty in the Film and Game programs at DePaul University.
