Coldplay, Kaiser Chiefs and Radiohead have recorded an album for the charity War Child.
They are among 21 acts who teamed up today to contribute tracks to Help: A Day In The Life.
Proceeds from the album will go towards helping children around the world whose lives have been blighted by war.
The first Help album was recorded in September 1995 and raised more than £1.25m.
This second album is being made to mark the 10th anniversary and is available to download online now.
The album will be released on CD on September 26.
