salyu × salyu ("salyu by salyu") is a pseudonym used by the singer Salyu for the release of her May 2011 album s(o)un(d)beams, a collaboration with producer Cornelius. The name "salyu × salyu" comes from Salyu's idea of using her voice as an instrument that creates a variety of sublimating sounds. http://www.salyu.jp/salyuxsalyu/main.html
