The first act from the BBC's Sound of 2009 list has been revealed, with electro-pop duo La Roux at number five.

The list is intended to highlight the best new music talent for the new year.

It is based on tips from 134 leading UK tastemakers, who named their favourite three new acts. A longlist of 15 artists was published last month.

One act from the top five will now be revealed every day this week, until the number one is announced on Friday. Last year, Adele and Duffy topped the list.

The Sound of 2008 top five also included The Ting Tings, Glasvegas and Foals.
