A longlist of fifteen rising artists have been published as part of the BBC's Sound Of 2009 survey, in which 130+ music journalists and broadcasters are asked to name their favourite new acts. I'm not sure they've done a longlist before. Presumably a shortlist will be revealed before the final winner is announced in January. The BBC's Sound Of survey is generally pretty good at identifying acts likely to succeed in the coming year - last year's shortlist included Adele, Duffy, The Ting Tings and Glasvegas.
Anyway, here's the long list in the order of that alphabet thing...
The Big Pink
Dan Black
VV Brown
Empire Of The Sun
Florence And The Machine
Frankmusic
Kid Cudi
La Roux
Lady Gaga
Little Boots
Master Shortie
Mumford & Sons
Passion Pit
The Temper Trap
White Lies
