Veli & Amos (SI and CH) are a multidisciplinary Slovenian-Swiss artistic duo dividing their time between Ljubljana and Zurich. They are known internationally for their distinctive pervasiveness and visual surprises that are founded in a language at the intersection of graffiti, artivism and performance and question the role of the artist, public space and contemporary marketing strategies. They are also the directors of the cult documentary Style Wars 2 (2013), which stars street art stars such as Banksy, Shepard Fairey and Seen. This time, they will create a mural on the 40-metre wall of the macadam parking lot at Metelkova using paint-filled fire extinguishers.
