Bjork is already preparing for her "massive" performance at Glastonbury Festival, she has said.

The experimental Icelander is one of several artists who have confirmed they are playing at this year's event and she is lining up an ambitious show.

She told BBC 6Music: “We have just started rehearsing and that is why I am in Iceland right now, we have a massive band, a ten piece brass band, we are rehearsing full on now, and I am kind of very excited but also very nervous which is a good thing.”

Among other contributors to her show, said the singer, will be percussionist Chris Corsano, collaborator Mark Bell and an Icelandic-Chinese concert pianist.
