Chthonic (sometimes typeset ChthoniC or ChThoniC) is a Taiwanese heavy metal band, formed in 1995 in Taipei. They have been called "the Black Sabbath of Asia." The group incorporates influences from traditional Taiwanese music including the classical Chinese instrument erhu (the band often calls it hiân-á [絃仔] in their native Taiwanese). The band's stated goal is to use their music to bring ancient history and mythology into the modern era via a pan-green focus, especially to build awareness of the myths of Taiwan and tragic events in that country's history (for example, those of the Seediq people).
