Mick Jagger, Joss Stone, The Eurythmics’ Dave Stewart and Damien Marley have been secretly recording together in a Los Angeles studio  for the past 18 months. The supergroup dubbed ‘Super Heavy’ spawned from a phone conversation between Jagger and Stewart discussing how they could replicate the ‘fusion’ of the many sounds that Stewart encountered while living in his home above Jamaica’s St. Anne’s Bay. A few phone calls later and the two settled on Stone, Marley and prolific film composer A. R. Rahman (Slumdog Millionaire, 127 Hours). Their album titled ‘Fusion,’ which consist of 18 tracks, has no release date but the band is hoping for a September release.
