Mariel Capanna (b. 1988) plays what she calls “games of remembering” as a way of reckoning with loss. Working from home videos and family slideshows, whose runtime is her constraint, the artist races to record fleeting memory images in oil paint. She scatters these flat, pastel forms like confetti across deep, atmospheric surfaces, creating compositions that are at once jubilant and wistful. For the Clark, the Philadelphia-based artist presents two new, site-specific oil paintings as well as a monumental, two-sided fresco. The fresco process is also defined by time constraints: since the time of the Italian Renaissance, the term giornata has referred to the area of wet plaster that can be painted in a single day. Mariel Capanna: Giornata marks the artist’s first museum solo exhibition.
