Zwei means "two" in German and, of course, the band consists of two members: Ayumu (vocals) and Megu (bass). They are produced by British producer Nick Wood, and you can hear their European influences. Their music is described as a mix between J-pop and UK rock. Zwei officially started in June 2003, but the two women actually met during the spring of 2002. They met at a live show, and Megu (of Pineal) asked Ayumu (of Cherry Feel) to become the vocalist of the band she wanted to create.
