Check out Montreal artist collective, En Masse, an incredibly talented group of painters and illustrators. Since 2009 theyve been creating intricate collaborative black + white murals on whatever surface they could find around town and now theyre doing international art shows and museum gigs. Heres a video of their outdoor contribution to Art Basel in Miami last year.
