Achour is thirty. Night and day, he walks. Rebellious soul, he crisscrosses Alger and its neighborhoods, stays at friends' houses and often leaves the city to meet the nearby montain in Kabylia, his alter-ego. In this environment, marked by war and terrorism, his resistance continues, mobile and ascending. Algerian hardcore-punk musician, Achour once screamed his anger against the country's regime and sang "Anarchytecture". But the movement died down, friends went their separate ways. His Facebook wall became his notebook, his window open to the world. It represents a scream aimed towards the echo of the mountains, between virtual wall, infinite facades of large complexes and the strata of mineral cliffs. A scream comes back at us.
