Djadja & Dinaz first got noticed in December 2014 for the wrong reasons. The video for "Laisse-nous faire notre biff" showed firearms, and four of the people in it were sentenced to three months in prison. The duo are Gianni Bellou (Djadja) and Azzedine Hedhli (Dinaz), childhood friends from the La Pierre-Collinet estate in Meaux, Seine-et-Marne, who met at the collège Henri Dunant.
After that they built everything on YouTube and on a steady run of albums with Carré-Music, starting with On s'promet in 2016, which went platinum within a year. Spleen (2021) was their first number one in France and passed platinum five months after release. Alpha (2023) and Terminal 7 (2025) topped the chart too. They are known for doing it alone, with almost no guest features across their records.
