Damian Marley and Stephen Marley are currently recording in Los Angeles, alongside Mick Jagger, as part of a charity project for peace supported by the United Nations.
The operation will result in an album due for release on 21 September, the UN's International Day of Peace.
Besides the Marley brothers and the Rolling Stones singer, many international artists are also involved in this initiative: Joss Stone, Allah Rakha Rahman (composer for Slumdog millionaire), the rapper Nas and Bono of U2.
