For the first time since the Rolling Stones formed nearly 50 years ago, Mick Jagger is part of a new band: Super Heavy – featuring Dave Stewart, Joss Stone, Damian Marley and Indian film composer A.R. Rahman. The band has quietly been recording together over the past 18 months, with their debut LP planned for sometime around September. "It's different from anything else I've ever been involved in," Jagger tells Rolling Stone. "The music is very wide-ranging – from reggae to ballads to Indian songs in Urdu."
