As if in confrontation with the endlessly tranquil extension of the sky,a crouching black rock lying on the bare mountain sometimes lets loose a scream,which nobody gets to hear.Its beat shoots straight through the unlimited space, apparently being the root power that penetrates the void,and specularly reflects on the bottom of it.Wild life, sound yourself, sound as you are.Refuse to be captured and sung in chorus,and bang this world.Brutal being, make a sound, as if striking.Rise to your feet as a solitary, single, soaring being,and bang this world.Now that you've become the sound, go to a true endless space.……"penetrating sound".
