For sound artist and architect Nathalie Brum, sound and space form a unity. Brum understands her site-specific installations as instruments for new forms of spatial perception and appropriation. She transforms sounds of hidden infrastructures into acousmatic compositions: two-dimensional, flowing and merging with the space. With Elisa Metz she founded the fanzine grapefruits about female composers* and sound artists* in 2019. Her spatial installation 'Gesang der Maschinen' (Song of the Machines) with stage and building equipment sounds backstage was realized in 2021 together with video artists Sebastian Wulff and Raphael Zöschinger in the interior and exterior space of the Wuppertal Opera House.
