Periscope is Unlock's partner for all things game audio. When scope or timeline requires extra hands, Unlock goes to Periscope.

Series credits include Empire, The Unicorn, Work in Progress, The Chi, feature films like Kickboxer: Vengeance, POOH: The Derrick Rose Story, Come As You Are, and brand advertising for Honda, Pepsi, and Groupon.

Unlock team members contribute music, sound design and implementation to Periscope when a project includes games or more advanced technologies to ensure the end experience is exactly what the client needs.

Between Unlock and Periscope, there's nothing we can't handle.

Elliot Callighan

CEO | Composition

Originally a violinist, Elliot began his journey in music and audio using the Suzuki method at the age of four. While he loved his experience on this instrument, it wasn't enough. 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 independent 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.
