Since its first batch of promising young talent was announced in 2003, the BBC's annual Sound Of poll quickly established itself as the leader of the yearly ones-to-watch lists.
And its tips for success have rarely proved wrong; previous winners of the accolade include Jessie J, Adele, Mika, Ellie Goulding and 50 Cent.
With this year's winner announced today as Haim - who were chosen by 213 critics, BBC tastemakers, radio hosts and DJs - Digital Spy has gone in search of more information about the rising band.
Sisters Este, Danielle and Alana Haim hail from San Fernando, California.
They are signed to Polydor, which is part of Universal Records.
Their music has been described as a blend of nu-folk and '90s R&B, or folk&B, if you like.
They started out by performing with their parents as the brilliantly-named Rockinhaim.
They've previously supported shows for Florence + the Machine, Ke$ha and Mumford & Sons.
They gave their best song so far called 'Forever' away for free as part of a three-track EP last year.
Their influences range from Nile Rodgers-produced disco (Donna Summer, Gloria Gaynor), emo-rockers Korn and Papa Roach, to Prince, Destiny's Child, Paul Simon, Whitney Houston, Thin Lizzy and Joni Mitchell. Phew!
Their current favourites are Kendrick Lamar, Jessie Ware, A$AP Rocky and Azealia Banks.
Their debut album is due out in "early 2013".
Harry Styles follows Alana on Twitter.
