Peter Connelly is a British game composer and sound designer known for his work on the intermediate Tomb Raider titles. Having been classically trained on the cello, guitar, and piano, Connelly has been passionate about music for as long as he can remember. He enjoyed the music of epic film scores while growing up and, as an avid fan of video games, was impressed by the quality of music featured on the Commodore 64. He soon realized that he wanted to dedicate his career to creating music for games and joined NMS Software in 1996. In collaboration with Mark Cooksey, he composed for the board game adaptations RISK and Battleship. He later created the techno score and sound effects featured in the shooter Mass Destruction.

In 1998, Connelly became a composer at British Tomb Raider developer Core Design. He initially assisted Martin Iveson with the sound effects design for Tomb Raider III.  He also created a composition intended for the last boss, but it was too late to add it to the game. For Tomb Raider: The Last Revelation, he personally created an expansive score bound by an electro-acoustic main theme. Connelly was inspired by both the unique level designs of the game and Nathan McCree's beautiful scores for previous titles in the series. He went on to create a darker score for Tomb Raider: Chronicles and work with the London Symphony Orchestra on Tomb Raider: The Angel of Darkness.

Connelly had an increasingly small role in Core Design after Tomb Raider development shifted to a San Francisco studio. After scoring Herdy Gerdy, Smart Bomb and Free Running for them, he left the company when it was sold to a British developer. Now a freelancer, he has worked as a sound manager at several simultaneous projects at Euthenyx. He has been responsible for selecting and implementing licensed music featured on a range of racing games, most notably The Fast and the Furious, Pimp My Ride, and Hot Wheels: Beat That. In other freelance roles, Connelly has had roles in the audio of Podz and Emergency Heroes, and Garden Party. He is currently working on several more titles in a sound management role.
