Exhibition "Collapsing Flat Waves — Robert Rehnig" is a sound installation exhibition in Riga at Radošā rūpnīca Veldze on 23 September 2026. The exhibition presents works by sound artist and composer Robert Rehnig, whose practice often explores simplified, perceptible processes through abstract soundscapes. The installations focus on the perception of space and, more broadly, on silence, with a recurring transition from hearing to listening. Leipzig-based Rehnig works with audiobooks, stage music and sound installation art, and researches the psychophysics and phenomenology of silence. The exhibition is open Wednesday to Sunday from 13:00 to 20:00. Address: Matīsa iela 8.
