Floor Jansen, born on 21 February 1981 in Goirle, Netherlands, is a renowned Dutch singer and songwriter with a versatile range of musical talents. She currently holds the esteemed position of the third lead vocalist in the Finnish symphonic metal sensation, Nightwish.

Jansen's journey in the world of music began with her membership in the symphonic metal ensemble, After Forever. She took on the role of lead vocalist in 1997, joining the band at the remarkably young age of 16. She continued to mesmerize audiences with her powerful vocals until the band disbanded in 2009. Following the dissolution of After Forever, Jansen embarked on her own musical path by forming the band ReVamp, with whom she released two albums.

In 2012, the symphonic metal giants, Nightwish, faced a significant change as their lead vocalist, Anette Olzon, departed. This led to the introduction of Floor Jansen as a temporary touring member during their Imaginaerum World Tour. Her extraordinary talents left an indelible mark on Nightwish, and in 2013, it was officially declared that she would be their permanent lead vocalist. In light of this pivotal development, Jansen made the difficult decision to disband ReVamp to devote her full attention to Nightwish.

Beyond her Nightwish endeavors, Floor Jansen expanded her musical horizons in 2018 by collaborating with Jørn Viggo Lofstad, the guitarist from Pagan's Mind, to create the dynamic hard rock duo known as Northward.
