“Semaphor” is a space-sound composition for two trendsetting instruments, which are theoretically and practically examined by the artists Susanne Fröhlich and Gerreit K. Sharma: a Helder tenor recorder and an icosahedron loudspeaker (IKO). If one understands both instruments as sound projectors, which can make sound sculpturally entangled tangible, spatially delimitable layers of sound and sound scenographies become possible, that had been not possible in this ensemble constellation until now. Last but not least, the question of the composable and tangible negotiation between an extended classical instrument (recorder) and an established apparatus circuit (loudspeaker/amplifier/computer), which has been reinterpreted by the latest scientific engineering findings and an advanced artistic practice, arises. This way of working is a contribution to an aesthetic practice that composes space by accepting space as a prerequisite for sonic-plastic material. How this material in the negotiation between Helder Tenor and IKO can be developed, documented and reproduced at the moment of the performance, is part of an ongoing research process, e. g. within the context of this esclab of both artists, here at esc medien kunst labor.

The esclab emerged from the encounter between artists, scientists and theoreticians from the most varied disciplines, which initially took place only as an exchange of ideas. The ensuing discourse was so promising, however, that on this basis over the years the esc media art laboratory developed a special form of cooperation which aims to use dynamic discussion and creation processes to directly influence the works that arise in this way. Each project is preceded by an esclab. In the course of this six-to-ten-month work phase, the project participants are invited to the esc media art lab to discuss possible synergies, spatial stagings, cooperation and the like. During this phase, the actual project emerges, which in this way remains open to decisive changes at each stage of the realization and implementation.
