Algiers, October 1988. A young, gifted and idolised painter from Oran, who painted about freedom on the walls of Algiers, is imprisoned. He was deeply moved by the scarified walls of his cell, eroded by human suffering. This poignant truth would influence his work. For a long time he painted at night-time, while surviving. Today, at peace and free, Sid loves nothing more than the light.  His painting is based on ordeal faced with the artistic medium. He scratches, tears, scribbles and recommences. He hasn’t forgotten the silence of the shadows, and its murmur has become deafening.
