The longlist for the BBC's Sound Of 2011 has been announced and it features fifteen rising stars recommended by more than 160 influential UK tastemakers.

They must not have had a UK top 20 single or album by 14 November 2010 and must not already be famous, for example by featuring in the final stages of a TV talent show or being a member of a successful band.
