Hope should appeal to people of all ages.
Eighties stars New Order and George Michael and former Beatle Sir Paul McCartney also feature on the album.
George recently said that many of today's pop stars didn't know enough about politics to make an anti-war record, but it seems he's keen to support this one.
The first War Child album, Help, was released in 1995.
It raised money for children in another war-torn country - the former Yugoslavia.
Hope is released on April 21.
