Animated since 2000 by Carlo Crovato, Radboud Mens, Jens Alexander Ewald and Geert-Jan Hobijn, Staalplaat SoundSystem ('Floating Mind') has organized a pre-programmed procession of tuk tuks with their horns hooting; has staged an army of washing machines and a ballet of vacuum cleaners; has grafted recycled engines on trees; has erected steel tubes resembling battleship cannons, converted into organs under the heat of burners; has built a Meccano in recycled plastic (bottles and PVC), which floats on the water and releases a plaintive drone ('Floating Mind'). These ephemeral experiences only last the time of an exhibition, an event, hence the need to document, to embed the sound of these singular creations. After 'Composed Nature'/'Yokomono-Pro' in collaboration with Lola Landscape Architects (AM Editions, 2011), this record is the second "sonic photography" of Staalplaat SoundSystem, which gives us an idea of some of its works.
