They are signed to independent record label Wati B, which is under exclusive license to Sony Music Entertainment France.

The first scenes of the group take place on the occasion of Fête de la Musique or town hall celebrations.

The group's meeting with Dawala, founder of the Wati B label, takes place shortly after in Châtelet-Les Halles, organized by H Magnum.

The first street album of the 3rd Prototype, entitled Le Renouveau, was released on 4 April 2008 under the Wati B label, in which we find the two previously clipped tracks, as well as featurings with Doomams on the title "Fils de lâche", Dry on Normal, Kizito on Survivor and R-Mak on "Gotham City", without forgetting, as usual, a good number of feats with Black M. Shortly after, R-Mak left the collective to devote himself to a solo career.

Directly after the release of the street album, the team worked on Les Chroniques du mois, their new songs as well as a freestyle were published every month between July and December 2008.

In order to promote the film Ong bak 2: Birth of the Dragon, the title "T'es bête ou quoi?"

The title of the album L'École des points vitaux is a nod to the manga Fist of the North Star (Ken the Survivor in France).

We can notice on the last page of the cover of L'École des points vitaux that Lefa writes on a blank sheet: “Next album: L'APO”.

The titles "Casquette à l'envers", "J'ai pas les loves", "Wati by Night" and the hit "Désolé" are a huge success with the general public.

They are also the subject of many parodies or other jokes, as in the after-sales service of Omar and Fred's broadcasts on Canal +, Willaxxx, or even in a clip by Kevin Razy and the other members of Sexion d'Homos.

They are among the first French artists to exceed one million fans (with Daft Punk and David Guetta) on the Facebook community site, in August 2010.

In this new video, they announce that the first clip of L'Apogée will be called "Mets pas celle-là", which will be released on 11 December 2011 on the official Facebook of Sexion d'Assaut.
