Damian Marley had joined legendary Rolling Stones musician, Mick Jagger, as part of the new supergroup Super Heavy.

Along with Marley, the Stones singer recruited singer Joss Stone, Eurthymics member Dave Stewart and producer A.R. Rahman to form the group. Rolling Stone revealed that the fivesome has already been recording together for 18 months, and plan to release their debut album in September. "It's different from anything else I've ever been involved in," Jagger told magazine. "The music is very wide-ranging –- from reggae to ballads to Indian songs in Urdu."

A source also told the New York Post that the group has completed their first single, filmed the accompanying visuals and are in the process of shopping around for a major label deal. Super Heavy is the first group that Mick Jagger has collaborated with, since his days with the Rolling Stones.

Damian Marley, who released the collaboration album 'Distant Relatives' with Nas last year, is currently touring in support of the LP. The two rappers recently announced that they would perform their final date of the year-long tour during Central Park's SummerStage concert series on August 11.

No word yet on a release date for Super Heavy's first single.
