Soyons Serieux got released on 14 Febuary 2011. It was with Malewa suite et fin, the most awaited album of 2011, but it couldn't get the succes that people were awaiting from it, due to combattans-phenomenon that just started a few days after it and everybody being focussed on it (the way concerts were getting blocked, musicians and polticians getting physical attacked in Europe and South Africa, etc.), people being focused on the preparation of presidential elections and problems with the promotion.
JB's rumba's were well received, but it didn't had that succes and his rumba's normally have when they get released. The biggest dissapointed at that time was the generique, from which people excepted alot for the way Mpunda was a huge succes in concerts.
