The installation is a collaboration in between Mika Vainio and LAb[au]. This sonic installation is constituted of six vintage tube-radios illuminated beneath by the wood columns they are placed upon.Two looping compositions of different length (18:17 and 15:57 minutes) are sent through radio transmitters and played on 540 kHz. 2x540mHz's soundscape is based on the temporal shift and spatial distribution of both compositions. The compositions are not only constituted of the typical hum and tuning known from radio's aural landscape, but also reveals the beauty of their hidden micro-sonorities.
