For fifty years, graffiti and street art have been challenging conventions and stimulating debate around our perceptions of what constitutes art. As the genre enters its sixth decade, this ground-breaking book presents a new interpretation of where street art and graffiti are situated today. Introducing the concept of 'Intermural Art' - art in between the walls - Rafael Schacter presents a genre at a key moment of transition. While many street and graffiti artists are still challenging the orthodoxies of the public sphere, an increasingly large group are reshaping the field by no longer furtively entering the institution, no longer slavishly reproducing exterior works inside, but instead attempting to merge out and in to create a form that articulates graffiti, street and contemporary-art influences. Through forty profiles of the leading proponents of this new approach from around the globe, Rafael Schacter presents a compelling analysis for 'Intermural Art' while also showcasing some of the boldest work being made currently.
