 While incarcerated, and based on his contacts with various hip hop artists, he was able to organize a number of musical events, particularly in Val-de-Reuil Prison where he was incarcerated, inviting hip hop artists to perform for prisoners.After getting initial approval in 2012 for a hip hop festival to be held in summer of 2013 at the Luynes Prison, with expected acts such as Cut Killer, Némir, Médine, Psy 4 de la Rime and Kery James amongst others, Mansouri proposed that the opening act be performed by a select number of prisoners presenting their compositions.The Shtar Academy project was formed as a result of this proposition.
