One of the few rock bands from Taiwan to gain exposure in North America, Chthonic are a melodic death metal group whose music employs elements of traditional Taiwanese music (including the use of the hena, an Asian instrument similar to the Western violin) and who frequently incorporate lore from their nation's history into their lyrics. Formed in 1995, Chthonic take their name from a Greek word meaning "of the Underworld," and feature Freddy Lim (aka Freddy, Left Face of Mardou) on lead vocals and hena, Jesse Liu (aka Jesse, the Infernal) on lead guitar, Hsiang-yi Yeh (aka Doris, Thunder Tears) on bass and backing vocals, CJ Kao (aka CJ, Dispersed Fingers) on keyboards, Dani, Azathothian Hands on drums, and Su-Nung, the Bloody String on hena. Chthonic released their first single, "Deep Rising" b/w "F—— or Die," in 1998, and their first full-length album, Where the Ancestors' Souls Gather, followed in 1999. Their second album, 2000's 9th Empyrean, was released in both English- and Chinese-language editions, as was 2006's Seediq Bale. In 2007, Chthonic released Relentless Recurrence and toured the United States as part of the long-running annual metal package tour Ozzfest; they were the first Asian metal band to join the Ozzfest lineup, and on nights off from the tour they also played club dates with Cradle of Filth and Nile.
In 2007, Chthonic were named Best Rock Group at the Golden Music Awards (the Taiwanese Grammys), with Taiwan's president Chen Shui-Bian presenting the group with its trophy. Chthonic returned in 2009 with their fifth album, Mirror of Retribution, based on the historic 228 Massacre, and followed up again in 2011 with Takasago Army (named after the Taiwanese soldiers who were forced to fight for Japan during World War II). Their seventh album — Bu-Tik (roughly translated as "the virtue of war") — was released in 2013 and increased their exposure to Western fans with English translations for songs such as "Set Fire to the Island." An acoustic EP of old favorites — Timeless Sentence — was released in early 2015. Stripped of the chugging riffs and screaming, it showcased the mournful and vulnerable sides of the group's intensely political lyrics and lush Chinese instrumental orchestration. In an appropriate progression of the band's political activism, Lim — running under his own New Power Party (NPP) — was elected as a representative to Taiwan's Legislative Yuan on January 16, 2016.
