Haha Real, a very site-specific installation by Rachel Rossin, opens at Buffalo Bayou Park Cistern in Houston. Illuminating a path through the subterranean reservoir with LED panels, the American artist draws on eclectic sources including The Velveteen Rabbit (a 1922 children’s book) and “The Creative Act” (a 1957 Marcel Duchamp lecture). Musician frewuhn contributes a score to set the mood for the 400 m journey, which culminates in a “cascade of uncanny sunsets within the darkness.”
