On April 3rd, Noorderlicht Fotogalerie in Groningen will launch an exhibition by American photographer Ken Schles. The exhibit combines Schles’ best known collection “Invisible City” (1988), with the recent “Night Walk,” which was selected by TIME as one of the photobooks that defined 2014. Together, they offer a ragged and compelling view of New York’s Lower East Side during the nineteen-eighties.
