After selling over 1 million albums, Black M delivers a third project titled "Il était une fois...", he resets the "counters" to zero and gives us a more personal and authentic album. This time, Black M gives the floor to Alpha Diallo to create these 16 new songs, written and composed like so many chapters of a book open to the world, he prioritizes themes drawn from personal experiences or those of his loved ones. For the collaborations, Black M brought together the cream of rap, we find Heuss l'enfoiré and Soolking but also Koba Lad, Niro, PLK and his buddies Big Flo and Oli.
