People of Philadelphia: visit an interactive thunderstorm! The giant new work by Chris Klapper and Patrick Gallagher is at Studio 2424; a thunderstorm contained within a series of large hand cast resin sculptures, each individual form is a unique instrument hanging 40 feet from the ceiling. Suspended just within reach and activated by touch, the viewer sets the symphony in motion by gently pushing the sculptural forms which trigger the various sound elements of the storm. Sensors relay individual recordings of thunder, lightning, wind, and rain with alternating intensities to a full-scale symphony of sounds.
