"The complexity of different points of sound observation in a space" - A sound installation in ausland

Jutta Ravenna uses the residency at ausland to experiment with positioning Leslie speakers in space. She will confront the pure sound of the rotating resonance bodies of the electromechanical leslie speakers and digital techniques (digital sound processing) as a work of art and at the same time demonstrating a piece of technology history. Four additional variations come up: rotating with sound, rotationg without sound, halting with sound and halting without sound. Controlling rotation velocity adds yet more sonic variabilty. So the application of rotating loudspeakers effectively generates a very complex soundscape for the moving listener.

The Leslie speaker is named after its inventor, Donald Leslie (1911-2004). Originally developed as sound effect add-on for the Hammond organ it was widely used in 1960’s pop music productions.
