DSLE is an immersive audiovisual environment that takes us to and beyond transitions in, and limits of, our visual and auditory perception. It explores carefully created interrelations between sound and light. Different models are being used to give light a spatial and time-based component comparable to the spatial behavior of sound. DSLE is using an octophonic loudspeaker setup and fourty four independently controlled led lights. The lights are shining towards, and therefor lighting up, the screen that surrounds the audience. The spatial nature of the setup and the detailed level of control creates the possibility to control and manipulate our perception of space. The behavior and artifacts of our senses form the starting point for the composition of a transforming space. Moments where sound and light appear to interrelate with each other are complemented with moments where the spatial perception of sound and light contradict with each other and lead to distinct ambivalences in our perception of space. Sections with very subtle, near invisible, changes are alternated with powerful moments that play directly with the retina itself.
