There is a very good Wiki page dedicated to German artist Hans-Peter Feldmann here. It makes a series of good, clear observations that describe his work well. 

The next in this artist's book series offers a chaotic compendium of movie stills, photojournalism, ads, amateur photos, pornography, art, scientific imagery, archival imagery, found photographs and more. Feldmann’s touch is in the sequencing. Sometimes its stories, sometimes only associations. Narratives are broken then fused, but there’s always the palpable energy of our times.
