Loops on a topographic surface, each slowly morphing. The loops are created by using the surface directly. As the center of the loops and the radius changes, new sounds emerge. Topographical data is a part of the danish laser scanned digital terrain model. The sample density is around 1.6 m, thus containing lots of information. You hear the rural area west of Aarhus. The bass is created by the valley and the noisy part occues as the loop circle iser over the city and the noise is generated by the buildings.
