Scottish rockers Biffy Clyro are to headline this year's Hogmanay line-up in Edinburgh.
They will bring in the new year at the Concert in the Gardens, the showpiece event of the capital's celebrations.
Pete Irvine, director of Edinburgh's Hogmanay, said: "Biffy Clyro are the UK festival band of the year. They've made us all feel good. And they're Scottish. What better way to see in 2011?"
Tickets will go on sale on Friday and further acts will be announced later.
Biffy Clyro came together at school in Kilmarnock, Ayrshire, in 1995.
Their latest album Only Revolutions has reached 300,000 sales in the UK and was nominated for the highly prestigious Mercury Prize.
Councillor Steve Cardownie, Edinburgh's festival and events champion, said: "Edinburgh's Hogmanay is envied across the world and this year, with Biffy Clyro set to perform, there will be no better place to be to bring in the new year."
Tickets are already on sale for Edinburgh's Hogmanay Street Party, featuring live music stages, giant screens and the famous midnight fireworks.
