Sigur Rós have revealed they are secret metal lovers.
Frontman Jón Pór Birgisson may be renowned for singing beautiful melodies, but in his youth he was more likely to 'Bring Your Daughter To The Slaughter' as a huge fan of, metal legends, Iron Maiden.
He told the Daily Mirror: "We met Maiden's Bruce Dickenson once on a show.
"He didn't believe we actually liked them, but I really did. I loved the energy, the power and the melodies."
But Jónsi attributes his initial interest in music to Liverpool's Fab Four.
He added: "My first memory of music is playing a Beatles album too fast on my parents' stereo. I used to love doing that - it's how I learned to play the guitar."
