Creating audio illusions and psychedelic imagery, disorientation and tricking the mind are two key concepts for this evening.

Cologne-based Marcus Schmickler will add to this year’s contigent of musicians that toy with our perception. From difference tones (an additional tone whose frequency is a mentally perceived difference of two played notes) to acoustic emissions produced by the cochlea, Schmickler’s interest revolves around the brain and its adaptation to multiple auditory stimuli. In his recent Palace of Marvels release on Editions Mego, Schmickler explores a new interpretation of the 1960’s "Shepard tone" discovery. When listening to a Shepard tone, we are faced with the illusion that the pitch is either continuously ascending or descending though it is apparently never reaching a limit. Starting from such phenomena, Schmickler’s multi-channel piece, "Fortuna Ribbon," twists the fundamentals of musical practice – rhythm, sound, and pitch.

New York-based filmmaker and musician Rose Kallal and London musician, esoterica writer and publisher Mark O Pilkington will also appear with their collaborative project. Kallal’s 16 mm film "Aldebaran," projected using multiple projectors, blends together with a semi-improvised soundtrack of dissonant drones and abstract analogue psychedelia to produce a thoroughly engrossing and disorienting experience.
