Sigh is regarded by many as Japan's leading extreme metal export, having released numerous highly esteemed recordings throughout their twenty year existence. Although originally a black metal band, Sigh became recognizably eclectic, taking influence from Romantic era classical music, jazz, prog rock, dark electronica and more. In May of 1990 three musicians attending the same college formed a band called Sigh. The lineup consisted of Mirai Kawashima on bass, vocals and keyboards, Satoshi Fujinami on guitar, and Kazuki Ozeki on percussion.
