Before there was Do As Infinity, there was only Nagao Dai. In his early days as a musician, Dai was a composer for an amateur band. One thing leads to another, and that band disbanded. Keeping his dream alive, Dai kept on composing songs and he sent them to more than 50 record companies in Japan.

Everything changed when Dai found AVEX, who hired him as a composer. He was immediately given a task to compose songs for Ayumi Hamasaki and Hitomi. But he never forgot his one dream: to have his own band.

AVEX gave him a chance to make his dream come true. Auditions were held, and he chose Van Tomiko as lead singer, and Ryo Owatari as guitarist. On September 29th, 1999, the trio released their first single Tangerine Dream, and held a live concert at the Shibuya.

After a few years, several singles and albums, along with video collections and recorded live concerts, Do As Infinity is still going strong. Although Nagao Dai isn’t as active as he was in the beginning (he doesn’t participate in promotional events anymore, such as video clips or photo shoots) he is still the main composer and the brain behind the band. He does, though, appear in concerts from time to time.
