I am an Icelandic singer-songwriter, composer, actress and music producer. I’ve been nominated for 13 Grammys, an Oscar and two Golden Globes (including one for acting). Best known for my expressive vocals and an interest in many kinds of music, as well as my eccentric costumes, I’ve sold more than 15 million albums. My most recent album, Volta, was released on May 8, 2007. Who am I?
