Know Hope (interviewed) and Aakash Nihalani recently took part in Vienna’s Blk River Festival. The event, which is composed of three parts – outdoor projects, an art show, and film festival – is the city’s first festival dedicated to street art.

Know Hope sent us this fantastic time lapse of a collaboration piece with Aakash alongside the waters of the Danube (known as the Black River because it originates in the Black Forest and empties into the Black Sea). After you’ve checked it out, take a peek at some more├é┬ástreet pieces, setup/installation, and shots of the opening reception after the jump.
