The CAT Open events held on MAK NITEs are continued with Elisabeth Penker’s sound installation “Rhythm / Language Transformations”. Elisabeth Penker studied sculpture at the Vienna Academy of Fine Arts and later worked for sound studios in Chicago and in movie post-production in London. Today, the artists lives in Vienna and engages both sculpture and music in her work. In her sound installation “Rhythm/Language Transformations”, she investigates overlaps of language and music and of image and spatial structures. On this evening, an acoustic examination is conducted inside the flak tower in its hermetic isolation and visitors are lead through space along strands of inter¬woven of sounds and noises. The composition of “Rhythm/Language Transformations” is structurally based upon the grammatical categorization of language which is deconstructed into minimal units and played over a non-linear five-channel matrix. Penker expands the sound installation with a performance in which she plays an instrument called “sonic structure”. The sound installation is supported by the electronic punk band Illegal Emotions (Ilegalne emocije), founded 2004 and for the first time in Vienna, whose music directly integrates elements of electronic, pop and punk culture.
