"We often felt like the strange duck on the festival bill because there was a woman in the band." How two modern metal icons united for a collaboration over a decade in the making

Tarja Turunen and Sharon den Adel looking at the camera seriously.

When Within Temptation and Nightwish released their debut albums in 1997, there wasn’t a name for the kind of music they made. Within Temptation’s Enter, released in April, took obvious influence from gothic metal bands like Paradise Lost, but its grandiose, elegiac compositions and symphonic undertones hinted at the direction the band would eventually take. Conversely, Nightwish’s Angels Fall First, released in November, approached metal from a different direction, drawing more directly and heavily on folk and classical music.

Ultimately, both bands would spearhead the symphonic metal movement of the early 2000s. But, anchored as it was around two charismatic women – Sharon den Adel and Tarja Turunen respectively – history tells us surely there must have been some rivalry. Symphonic metal’s answer to Blur vs Oasis perhaps, or Mustaine vs Metallica?
