kymat.de is more informative than the collective's Instagram, because it shows how the work is actually funded. There are interactive sound installations for exhibitions and events, audiovisual live performances built on water, light and music, fine-art prints of water sound images, commissioned personal sound images made from a voice recording, two vinyl releases of 500 copies each, and water sound bowls co-developed with Peter Hess.
The exhibition list is the credible part: Art Basel Hong Kong, Milan Design Week with Hyundai, Nuit Blanche Paris, Fusion Festival.
One flag. The album Good Vibrations is described as containing sound-therapy elements, and the Peter Hess name belongs to a German singing-bowl therapy brand. The site does not present evidence for therapeutic effects and we would not read any into it; the installation and print work needs no such justification.
