Since the early ’90s, Kritchev and Ban dabbled in home-taping (and also engaged in collecting and listening to all kinds of music), and later joined forces for joint action. Kritchev vs. Ban, taking as a basis the principle of no music / no instruments, essentially positioned themselves as amateurs, non-musicians who use their love to the sounds and the easiest ways of sound as a starting point of his «creative» activity. To create the records used household radios — radio-gramophone, amplifier, tape recorder, microphone, TV, music player, player records and CDs.
