Why street artists seem to feel the need to see everything in terms of a war-zone is quite beyond me. Grenade Art are a "frontline" street art collective made up of eight designers, illustrators, painters and sculptors all of whom have been actively involved in street culture for the last twenty years.
Grenade Gallery, opened in June 2008, is their first permanent gallery space and it's just near Ladbroke Grove. Exhibitions last around a month, and are frequently "explosive".
