Granville Island's OSGEMEOS mural part of Vancouver Biennale

Brazilian artists OSGEMEOSare busy transforming several concrete silos on Granville Island as part of the 2014 2016Vancouver Biennaleartistic exhibition.

Otavio and Gustavo Pandolfo the artist twins known as OSGEMEOS have been working on the 21 metre high silos, expected to cover approximately 7000 square metres with their art.

Before they settled on the site owned by Ocean Concrete, the artists spent several days touring Vancouver looking for a suitable place to host their work.

"What they chose were the silos," said Vancouver Biennale founder and president Barrie Mowatt. "They thought they were the most interesting surfaces to work on.

"If they were going to do a project in Vancouver, it had to be the silos."

This stands as the biggest mural of the twins' career, and it can be viewed from 360 degrees, with vantage points on the Granville St. Bridge, Granville Island and across the water in Yaletown.

Ocean Concrete were quick to get onboard with the project, expected to be completed early September, while the artists who donate their time are working 10-12 hour days to get the project done on schedule.

There is an indigogo campaign to try and cover $125,000 in hard costs. So far, the campaign has raised $31,576.
