New Rooms [Helga 
  de la Motte-Haber]: In Rolf Julius' works, sections of landscape, walls, 
  and rooms are acoustically elaborated, emphasized, and transformed; yellow and 
  black sounds, small sounds, and sounds "way up above" play a role. 
  Rooms display new dimensions, and at the same time sounds call their characteristics 
  into consciousness. The peripheral perception of size and brightness becomes 
  clear perception in the artistically determined system of coordinates. In listening 
  to a window or a wall, distance becomes subjectively clear, closeness and distance 
  gain presence. The rooms are no longer merely geometrically measured, but become 
  spaces of experience. Julius has sometimes used this step forward from quotidian 
  perception in quietly shifting layers of sound to create still rooms, even if 
  they may be located in a loud site of heavy traffic. When one directs one's 
  attention to the minimal changes in the sounds, the noise disappears or is pushed 
  to the edge of awareness. Such concentration creates calmness. It makes a space 
  of contemplation possible. Julius has invoked the image of an "acoustic 
  hole" to describe this step forward from loud surroundings through meditation 
  in his quiet sounds. The protective zone of calm, where one can dig in, changes 
  the formats of the surroundings. The sounds turn rooms into sites that can be 
  measured subjectively.
