A list of 15 of music's most exciting rising stars has been announced for the BBC's Sound of 2011 feature.
Many of the artists are likely to feature on UK music radio next year, with the winner and top five being announced by Radio 1 in early January.
Ellie Goulding came top of last year's list. Other winners in the list's nine-year history include Little Boots, Adele, Mika, Corinne Bailey Rae and 50 Cent.
George Ergatoudis, Head of Music at BBC Radio 1 and 1Xtra, said: "There are many lists of hotly tipped acts, but I believe the BBC's Sound of… list now stands out as the definitive one, thanks to the rigour applied to its compilation and its comprehensive range of contributors including taste-makers from radio, TV, newspapers, magazines and online.
"Over the years it has helped music fans discover some fantastic artists and while some have disappeared without a trace there have also been notable successes including Dizzee Rascal, Keane, the Kaiser Chiefs, Plan B, Adele and Florence And The Machine, to name just a few."
