Tarja Turunen
Until the end of their collaboration, Turunen's singing was a trademark of Nightwish. She was known as the face and voice of Nightwish while bandleader Holopainen was the soul. Turunen was seen as a key to Nightwish's success. She is respected by other musicians of the metal genre and is an influence on their work; for instance, Simone Simons of Epica names her as her inspiration to study classical music and apply that vocal style to a metal band.
