Pyramids builds on the Polaroid aesthetic of Mike Slack's previous books, Ok Ok Ok (2002) and Scorpio (2006), rounding out a handsome trilogy of stand-alone volumes that together contain 123 pictures. This collection records everyday details of what could be a recent past or a very near future—a dust storm in the desert, simple geometry, stairways and windows, schoolchildren on a field trip—quietly dramatic scenes energized by a sense of anticipation rather than nostalgia. Presented as physical artifacts of (fictitious?) events to be deciphered by the viewer, the pictures also document the travels, observations and graphic fixations of the photographer, centering on a set of three identical early-70's office buildings (in Slack's hometown of Indianapolis), from which the book takes its title.
