As a tangible continuation of Residuum, a book of analog photographs called Dérives or How a fragility was overcome (but not in this book) was created.The book introduces a variety of color as well as black and white analog pictures and poetry. It originates from four years of walking (psychogeographic walking) different cities around the world (Toronto, Luxembourg, Eischen, Amsterdam, Brussels, Nice, Arlon). It portrays analog pictures of overlooked urban infrastructure (ranging from stacked white chairs in a dark alley on a Sunday, a fence thrown into the lake, to pastel yellow, eerie detritus containers isolated by the train tracks) and offers an alternative, phenomenological positionality towards our communal urban environments, that is, one of poetic care and pure material aesthetization.
