MICK JAGGER is taking some time away from the ROLLING STONES to work with a new group called SUPER HEAVY.

The band also features:  Former Eurythmics superstar Dave Stewart, Joss Stone, Damian "Son of Bob" Marley and A.R. Rahman, the guy who scored "Slumdog Millionaire".

(Amazingly, this is NOT a joke.  Their first single will be an updated version of the Eurythmics' classic "Sweet Dreams".  OK, that part was a joke.)

"Rolling Stone" says that for the past year-and-a-half, Super Heavy has been "quietly recording together."  (That's nice.  I'm sure their neighbors appreciate the consideration.) (???)

Their debut album is supposed to come out in September, but there aren't any concrete details yet.

Mick says, quote, "It's different from anything else I've ever been involved in.  The music is very wide-ranging... from reggae to ballads to Indian songs in Urdu.

"We wanted a convergence of different musical styles.  It's a different kind of record that what people would expect.  It's not all weird and strange though.  I think Stones fans will think it's a bit odd, but they'll find most of it accessible."
