These Swiss folk metallers imbue old forms with new sounds, combining the sheer power of screeching, melodic death metal with the unique timbres of Celtic music and employing unusual-for-rock instruments like bagpipes and the hurdy-gurdy. A forceful collective that came together in 2002, Eluveitie explores Celtic mythology and culture in tracks like the weirdly catchy “Inis Mona” and the heavier, black metal-influenced “Rebirth.” Although the group has rotated more than two dozen musicians over the years, its heart and core has always been Chrigel Glanzmann, who wields countless instruments with a musical sorcery that few can match.
