Corum Watch Bubble 52 Booba L403/03372. Bubble rap with Booba. The partnership between Corum and Booba was an obvious choice for Corum. Symbols of their time, Booba and the Bubble have constantly moved forward and dared to assert their creative differences. By uniting an audience from seemingly disconnected generations, origins and backgrounds, they have become standard bearers for a new vision of the future by taking possession of it. This drive and need to move forward characterise the Bubble spirit. It is this same power that makes Booba one of the most important figures in francophone rap.
