If you saw Jack Pierson’s “Some Other Spring” in Los Angeles, you might believe the show to be about that place. On the level of the facts, you’d be wrong. Images in the exhibition were taken in a variety of locations: Egypt, Las Vegas, southern Spain, Yves Saint Laurent’s Paris apartment…the specifics hardly matter. Pierson’s artworks are of a piece in terms of the sensibility that created them. Like the highway billboard advertisements that form one aspect of their provenance, he presents his luscious pigment prints as blown-up posters, unframed and complete with folds typical of far less valuable pieces of paper. Helping to nail down a more exact location for the work are the artist’s trademark text pieces, which consist of words assembled out of letters from commercial signs. Eternity is the relevant time frame here, or, in Pierson’s words, A THOUSAND YEARS, as spelled out in letters on the wall.
