Having joined forces with fellow French-Algerian rapper LIM on 2009's collaborative effort Evolution Urbaine, Zeler went it alone in 2012 with his first solo full-length album, Tremblement de Terre. Released through the Tous Illicites label, its 19 tracks include collaborations with several emerging MCs including Boulox ("Jai Su Grandir"), Alfa Ecko ("Mon Quartier"), and Issaka ("Ma Communaute"), alongside the lead single, "Sur le Terrain."
