L'Écrasement de tête (Head Crush) is the first street album by the Sexion d'Assaut collective (not taking into account the discography of the 3rd Prototype, the internal group of the Sexion d'Assaut).

Lefa said in a magazine in 2009 that the 3rd Prototype did not exist since the release of The Head Crush, therefore the Sexion D'Assaut is a band in its own right and no longer a collective.

This disc will be the first to experience significant success, and really increase the group's notoriety among the general public.

This street album allows them to start their first tour with many dates all over France in full venues, to their surprise.

On this street album, we find exclusively the members of Sexion Assault or Wati B, namely Maître Gims, Lefa, Barack Adama, Black M, JR O Crom, Doomams, and Dry, with the exception of Ania who Doesn't belong to Sexion Assault or Wati B.
