developing and researching alongside the radio program series, this [multi-channel concert] demonstrates the results of the investigation about the fundamental concept of digital, the data of sound, the sound of data. it is performed in a pitch-dark space as a multi-channel concert with a matrixed setup of specific loudspeakers, which forms a unique spatiotemporal sound field to listeners. the experience is straight-ahead physical, and is a series of experiments to test one's potential how (much) he/she can perceive and decipher the infinite numbers of data-codes in the blind state.
