Jason Kelliher is a UK-based composer and sound designer specialising in music for video games. He has collaborated on a wide range of projects, from fast-paced Game Jam teams to ongoing MMO developments, gaining experience across different scales and creative environments. Alongside his collaborative work, he has independently released multiple singles, EPs, and albums, steadily building toward his goal of becoming a full-time musician and dedicated creator of sound.

With a strong affinity for orchestral fantasy and sci-fi, Jason crafts music that ranges from memorable, cinematic main themes to immersive atmospheric pieces and impactful stingers. His skills have been developed through years of hands-on experience, as well as formal training, including completing Jason Graves’ Music Composition for Games course, where he achieved top marks and earned certification.

His credits include serving as lead composer and sound designer for an Itch.io development team that evolved from a single Game Jam project into a year-long collaboration. He was also part of GameCult during the early development of Atheria, an upcoming space-based title, contributing as the project’s composer.
