The rendering up top shows the sort of scene that visitors can expect if they wander into the 1920’s leaking-water-reservoir-turned-public-art-space buried alongside Buffalo Bayou after December 10th (and before next June): Venezuelan artist Magdalena Fernández’s 2iPM009 projection, adapted from flat-walled origins to fill the 2-acre space (and going by the name Rain). As for what they’ll hear — that’d be an accompanying soundtrack of snaps, claps, and other meteorologically-inspired noisemaking from Slovenian choir Pertuum Jazzile. The original piece is part of the Museum of Fine Arts’s permanent collection; the adaptation will be the first temporary art installation in the column-studded space, which opened for tours in May.
