The films Loop consists of two Super8 films, each film consists of 3.600 single frames and enfolds 2.880 metre of Chicago’s elevated railway line, called Loop, in my live performance. The elevated railway was captured from below in a single image process in a double film loop. Each film loop was paced against the one-way and filmed overhead directly under the course of the elevated train. Black-exposed cadres mark the moments when it was impossible to film due to the street situation and the number of steps was translated into black-exposed cadres. The double film loop of the live performance took 9 hours for 2x 2.89 kilometers to document 7,200 single images. The Loop is a colloquial term used by residents of downtown Chicago. It is the second largest business district in the United States after Midtown Manhattan and has one of the highest university densities in the world; Columbia College Chicago, Roosevelt University, DePaul University, The School of the Arts Institute of Chicago, etc. The term loop does not originate from the elevated railway, but from a funicular that ran around the square before 1900. Today the Chicago Loop is circled by the L-elevated railway and the route has always been the site of demonstration trains and the route below the elevated railway is a place to sleep and shelter for homeless people in Chicago.
