Jano Doe uses homebuilt modular synthesiser to create sounds exploring the limits of our auditory perception, incorporating extreme frequencies, volumes and sound event timescales, frequently crossing the barrier to physical sound perception. This sound is defined by inversions, creating the notion that the instrument is controlling the instrumentalist and where the formally sonorous becomes a representation of electrical, physical phenomena even before it is sound. Using intuitively conceived module arrangements, chaotic systems with fragile equilibria occur, always sweeping closer to the catastrophe point.
