The artistic emancipation of noise in the sense of organised sound effects was achieved as early as 1913. At least since the technological development of sampling one can not think of popular music without the notion of organised noise. At four exhibitions held at the Chemnitz gallery »Voxxx« between April and September 2002 musicians experimented with electronically generated tones in the context of an artistic space. So unsynchronised film projectors (Weltecho was also the name of a former cinema in Chemnitz) for example created rhythmic structures for sound oscillations.

The curator of »Weltecho«, German artist and musician Carsten Nicolai, stands for many instances of interaction between music and the fine arts and is well established in both disciplines. Nicolai helped set the wheels in motion for »Weltecho«, in which, amongst other things, the ten-year history of the Voxxx project - an amalgamation of film, music, theatre, the arts and communication - is reflected upon.
