With its complex network of movements intricately linked through time and space, Thomas Hauert's choreographic language could be seen as pursuing the tradition of abstract dance. However, it is entirely through improvisation that this strongly polyphonic writing comes to life on stage. Hauert's work is remarkable for its ability to weave order out of disorder, form out of formlessness, and community out of distinct individuals, all the while taking advantage of the tension and attention offered by improvisation. The choreography acts as a microcosm in which individuals must constantly negotiate between their own freedom and their determination to relate to others.

The matrix of „You've changed" is movement, or more precisely a choreography unfolding as an unpredictable but integrated system without a central directing agent. Which means that the dancers are at each moment responsible for inventing and performing their own movement material, as well as initiating and developing all group structures. They must adapt their individual roles within a group constellation whose mechanics are constantly changing.

As in a chain reaction, this improvised choreography formed the base for the creation of a video, then a music, then another music, then new improvised movement, then lights, all these proposals finally answering each other on stage. Here, in other words, a self-structuring choreography becomes the structure on which everything else is built : the individual creative decision-making, with its imperfections too, as the foundation stone for a highly complex and polyphonic piece. One could perceive here a longing for form in times where form is - perhaps rightly so - distrusted for its authoritarian and simplifying arbitrariness. Hauert doesn't design form but sets up processes that have an inherent will to form. Form always emerges, often surprisingly, but never quite gets completed.
