Genki Rockets
In 2006, Mizuguchi pursued his love of technology and electronic music, founding the band Genki Rockets with a consistent group of collaborators, including songwriter and producer Kenji Tamai, as well as singers Rei Yasuda and Nami Miyahara. Mizuguchi would write all of the album's lyrics and contribute melodic ideas to Tamai, who would then work on the tracks in the studio. Described as a 'hybrid unit' by Mizuguchi, the vocals of the two singers were digitally combined to sound like one singer, while Rei represented the visual identity of the 'band.' Not unlike the band Gorillaz, Rei's alter-ego, 'Lumi,' was conceived as a 'virtual idol,' except in this instance, unlike Hatsune Miku, Lumi is based on a real human girl (Lumi would later go on to become a character in Mizuguchi's video game, Child of Eden). Genki Rockets has thus far produced two albums, ' and ', consisting primarily of electronic pop music, sung mostly in English, with occasional Japanese phrases. Tamai's music company Agehasprings describes Genki Rockets as an early virtual Youtuber.
