The people behind ComDomínio Filmes and Filmes do Bem bring a brand new documentary to the big screen this winter - A Arte Urbana - showcasing grafitti's continuing ascent and recognition within the realms of the city's art scene. Relatively young in comparison to the likes of that which transformed London and New York in the '70s, the Brazilian touch is nevertheless as imaginitive as it is distinctive, largely unencumbered by local councils and governed instead by its own rules, which the film goes some way towards demystifying. To help raise funds for the film's release, artists including Bobi e Bunys of graf school Espaço Rabisco will converge on Parque dos Patins to create two huge murals destined for auction, perfect inspiration for anyone who wants to get their own creative juices flowing.
