Cielbleu is a Japanese pop group consisting of the Yamashita brothers, Sean and Leon, and Mizuno Shintaro, going under the name Sin. They have so far released one single, Forever. The single was originally only sold at their debut live performance but sold so well that their agency made it into a limited release so it could be ordered online by those who live in Japan. <a href="https://www.last.fm/music/cielbleu">Read more on Last.fm</a>.
