CHIKATETSU, the "underground iron", the subway system that is the heart of public transportation in the large cities of Japan. But this music is about those hyper-cultural and psycho-emotional spaces common to all aspects of modern life: isolation, solitude within crowds, private moments of sentiment, thought, feeling, memory, place, and the relationship of this highly individual experience to society and an ever-changing 21st century world. The music of CHIKATETSU is the soundtrack of these experiences - music for the inner listener. Tim Gerwing's work investigates the musical nuances of these experiential modulations, exploring abstract and cross-cultural scenery creating and created by a hyper-real inner reality. The mirror of self that illuminates the Other. Using ambient textures and modern musical motifs, non-linear narratives, fractal audio perspective, and allegorical sonic imagery, Gerwing creates contemplative and immersive sonic environments ments which suggest the expansion of culture and of the modern self. The ear hears, the mind accentuates, the heart listens. In this synaptic map, sonic objects are manifest calculations of the creative networkings of the mind - a mind that uses the body as a framework to explore ideas, patterns, and emotions. Within this musical environment, the self is immersed in memes and memories both experienced and imagined.
