Art is communication, art is connection, art is even war. In the case of Grey City, a documentary about São Paulo and the city’s street artists, the terrain for this art is the street, more precisely the walls in the street.

In the 1980s, São Paulo took the world stage as the epicenter for urban visual street art known as pixo — graffiti and tagging. Its antecedents, Pixação, “wall writings”, originated in São Paulo in the 1940s and 50s when citizens painted political statements in tar on walls in response to political slogans painted by political parties. Pixo’s evolution through to today has maintained that spirit of dialogue and defiance—a kind of urban calligraphy where some of São Paulo’s most marginalized endeavour to tag as high as they can, in as many public places as possible, incontrovertibly asserting their existence as a form of challenge to the city’s privileged who consider pixo ugly, ignorant, and illegal, much in the way they view the pichadores (the pixo makers) themselves.

The 80s re-emergence of pixo was an organic extension of other street art forms like hip hop and break-dancing. Such was the route for Os Gêmeos, the twin brother graffiti team featured in Grey City. With the same nimbleness of their breakdancing, identical brothers Otavio and Gustavo moved toward paint, starting first with pixo and then expanding their work into more pictoral murals. Today, their early pixo style can still be found within their murals, and the impetus to connect and converse with their city is at its heart.

Os Gemêos is out to communicate, to engage, and to contribute something positive for_ 2014-08-22 15.30.47 the public good—these are their guides. Producing their work during the day is critical to the process and to their pieces: how else will they know what’s going on, what they need to say, and to whom? How else will they connect directly with people and engage in real time? That’s how they see it. And what they encounter speaks back to them through the smiles and joy returned by passersby—this enthusiastic feedback loop affirming for them that they’ve honoured their vocation and their destiny.

Graffiti, however, also operates within the framework of the city’s regulatory, mercantile and political interests. So the war this artform engages in is often with the clean up crews contracted by City Hall to paint over the murals not deemed to be “artistic”—so, armed with grey paint, a subjective and anonymous army disappears the art, randomly and arbitrarily. However, in a metropolis of almost 20M people that sprawls across almost 8,000 square kilometres (the largest city of the Americas), the effectiveness of the clean up efforts doesn’t really keep pace with the artists, and so a kind of dialogue reverberates between leagues of creative resistance and the amorphous apparatus mobilized to squelch it.

This is where the graffiti movement truly embodies its role as a public art. No one possesses it, directly challenging the fundamentals of capitalism, and no one really controls it either, though many try and wish they could. In the case of Os Gemêos, their rigorous code of conduct keeps their work “clean”, in the sense that their concern with public good means shunning any form of negative messaging, and their tireless commitment to producing such work, in proliferation, eventually attracted international attention, rendering their colourful contribution to the city’s walls more and more challenging to object to.

Os Gemêos’ progressive rise to worldwide acclaim has ironically jettisoned their work to the reaches of national sanction too: they were commissioned to tag the plane of Brazil’s national football team competing in the 2014 FIFA World Cup. Perhaps, though, this is a most apt illustration of remaining true to the artists’ animating values—speaking truth to power—in this case attaining lift off with jet engines; though, told not to paint the jet’s engines covers, they did it anyway, ever true to another animating force of the grafiteiro, tagging where authorities don’t want you to. Perhaps not quite biting the hand that feeds them, we could fairly say that Os Gemêos is willing to paint it.

Here in our own grey city, Vancouver is now home to the latest Os Gemêos piece, Giants, thanks to Vancouver Biennale and their partnership with Ocean Cement on Granville Island. Giants is an ongoing Os Gemêos project, adding Canada to the Giants growing international family of Greece, USA, Poland, Portugal, the Netherlands, Brazil and England.

As Os Gemêos believes, “Every city needs art and art has to be in the middle of the people”, so Vancouver now has art, in the middle of the city, and this art happens to be a kind of people in its own right—Giants—an excellent symbol of art’s enduring heart, which is 3 dimensional, multiple, central, colourful, and gigantic.
