An album of music from stars including David Gray, Ash and REM is to raise money for refugees in the troubled Darfur region of Sudan.
Badly Drawn Boy is one of many artists to contribute to the album
Fighting between government troops and rebels for the last 18 months has led to around 50,000 deaths and 1.4 million people fleeing their homes.
The UN has called the situation the world's worst humanitarian crisis.
The album, featuring 14 exclusive tracks, will be released on Friday on Oxfam's bignoisemusic.com website.
In 1985, Bob Geldof raised millions of pounds for the victims of famine in Ethiopia with Live Aid.
The hit single Do They Know It's Christmas (Feed the World) sold more than three million copies and became the blueprint for other fund-raisers.
All artists and record labels donating tracks to the Sudan album - which also features Badly Drawn Boy, Jet and Faithless - are forgoing their royalties.
Damon Gough, aka Badly Drawn Boy, said: "Men, women, and children are still
dying every day in Sudan.
"People like us might not have the power to stop the violence but at least we
can try and help the people affected by it.
"Oxfam is already saving lives, the least we can do is help them to save more."
The conflict erupted in early 2003, when two African movements rebelled against the Khartoum regime, accusing it of siding with the Arab tribes in disputes over scarce water and arable land.
The refugees have been driven from their homes, primarily by the pro-government Arab Janjaweed militia, and are now living in 139 camps across Darfur and nine camps across the border in Chad.
Food and medicine are desperately needed in the camps, which are scattered across
a region the size of France.
The album - which is only available by internet download - will sell for £7.99, with £5 going directly to the Oxfam Sudan appeal.
