BROM is a hall-filling sound installation. Motorized instruments are hanging from the ceiling, creating a sound sculpture in the space. As a visitor you envelope yourself in slowly changing harmonium sounds.

An old spinning choral humming top that De Groot ones found on a flea market was the start for the immersive installation. Fascinated by the colorful children’s toy making a 3 chord melody she researched its patented technique, the history of the top and the free-reed instrument.
