When Gaijin Games set about infusing the Bit.Trip game series with compositions by notable chip music artists, they anticipated a growing trend of collaborations between indie game designers and the retro DIY music scene. This weekend Bit.Trip Runner contributors Anamanaguchi will play the Penny Arcade Expo in Seattle, while Bit Shifter of Bit.Trip Beat and Nullsleep of Bit.Trip Void appear at Blip Festival Tokyo. Tickets to the Japan chip music concert will be available at the door of Koenji High, located in the Suginami Ward of Tokyo, the afternoons of September 4 and 5.
