“Pink Noise,” a major Troika solo exhibition, opens at Langen Foundation near Neuss (DE), foregrounding the Franco-German trio’s artistic reflections on mediated nature and our dis/orientation within it. The show explores “how our perception of ‘nature’ is calibrated to digital media’s frequencies and spectra,” write curators Dehlia Hannah and Nadim Samman about their selection of new and recent works. As new technologies invade the human sensorium, they ask, how does our environment change?
