Yui Onodera founded CRITICAL PATH in 2003. It is digital experiment sound label that is minimal, electro acoustic, static ambient, and sonic art. Minute sounds that exists there as cause that composes environment. It listens to the generation of the sound and the process of a silence, and it explores that relationship between the sound and listening. Very minimal, ambient sound create a complex texture, and it makes the listener need attention and the concentration. It means the lead into a deeper area. A new way to listen to the sound is presented.
