What is this?

A couple of months Itunes advetised a group called "Superheavy" on the front page, me as a curious mind, liked the album cover and got to know more about the band. Then I read it is Mick Jagger´s band and that sime guy from the "Slumdog Millonaire" BSO (BTW big Windmill Quality Stamp both on the film and the songs). Anyway I forgot I had downloaded this album until today when I went to the "Bought" Section and found a nice suprise. The band is a recommendation as it is awesome. The heavy naes in the band appart from Jagger ae Damian Marley, A.R Rahman and Dave Stewart.
