On the territory of a modern city bioinert soil systems become part of the urban technobicenosis and irreversibly change under the influence of many anthropogenic and technogenic factors. Urban soils and techno-soils, encased in the armor of asphalt and paving slabs, are also formed under the influence of constant vibrations from various types of electromechanical systems. Urban transport, ventilation and air conditioning systems, large and small industrial enterprises create constant vibrational fields of sonic and infrasonic frequencies which propagate in solids at high speed and carry a huge amount of energy absorbed and dissipated by the soils.

The first part of the sound performance "Techno-soils. Vibrofabricat" is dedicated to working with vibrational fields of urban techno-soils within the territory of Fontanka river, St Petersburg. The streams of mechanical energy captured with the geophones become audible when the equilibrium states of the author's electroacoustic system of the Phonotrone type are violated.

The second part of the sound performance "Techno-soils. Vibrofabricat" is dedicated to working with vibrational fields of urban techno-soils within the territory of the Arrow of Vasilyevsky Island, St Petersburg. The streams of mechanical energy captured with the geophones become audible when the equilibrium states of the author's electroacoustic system of the Phonotrone type are violated.
