With her autobiography for Rizzoli still in the making, like her upcoming album, “Matangi”, M.I.A. has just signed with Roc Nation. While Interscope will still be her label for the international market, the artist inked a deal with the joint venture of Jay-Z and Live Nation, which will take care of her management. It will enable her to take even more advantage of her popularity, and will also make collaborations and the exchange of creative idea with other Roc Nation family members, like Rihanna and Santigold, a lot easier. Now we just have to wait for new music.
