Dutch symphonic metal band founded in April 1996 by vocalist Sharon den Adel and guitarist Robert Westerholt. They have always been classified by critics as gothic metal and symphonic metal, although each album contains other influences outside these genres. Their most prominent and well-known sound is described as symphonic metal, although their earlier material, such as debut album Enter, was mostly gothic metal, with Enter also having a hint of doom metal. In an interview, den Adel said they fell into a symphonic rock genre with various influences. In a later interview with Dutch music platform 3VOOR12, den Adel stated that "we consider ourselves more a symphonic rock band ... in my opinion, we are no gothic band".
