Comprised of a team of seasoned and creative individuals with years of experience in video game production as well as music, animation, lighting, pipeline development, debugging, web design, and rawking out, Bombsite Studios is the perfect choice to chart your original music for the Rock Band Network.

Gamer Beats was formed by a small group of video game industry professionals, with design and production experience spread across such companies as EA, THQ, and F-I. We are all quite crazy about music and Rock Band, and so decided to pursue our passions and become a Rock Band charting group. Gamer Beats will initially focus on bringing well known bands in under-represented genres to the RBN, in addition to helping indy bands we love share their music with a wider audience.
