Algerian-born photographer Mohamed Bourouissa is interested in systems, in how society—and particularly subcultures—are structured. For his project Horseday (2013), he worked with a local Afro-American horse riding community in Philadelphia. He was fascinated by the status of these “urban cowboys” and organised a competition with artists and riders to find the best decorated horse. Bourouissa translated this event into a series of photos, a two-part video, and several sculptures. Both scenes from everyday life and the staged event were recorded. In his preparations, Bourouissa made many sketches and draft compositions, which are also included in this book.
