And apart from snippets she's heard on the radio, Tarja has heard none of the band's material since then - and says she has no desire to seek it out. She tells Metalpaths: "I haven't been listening to their albums - I haven't been interested in listening to their albums. I don't know the music. I heard some songs on the radio, but that's all I know."

Tarja's replacement Anette Olzon was herself replaced, by Floor Jansen in 2012. And in her solo career, Tarja has resisted the temptation to live off her Nightwish glory days.

She adds: "Of course, it's a part of history - it's a very important part of my musical history. It brought me where I am. I don't have any problems with that. It really showed me a totally new direction musically in my life.
