Everything choreography is concerned with, is already known. It might be forgotten knowledge, but it is never new. Choreography is a way to trigger out of amnesia, through action, questions and reflection, what is already known. It readdresses the well known, so it can be seen from new angles, get reacquainted with and understood better.
In that sense, repertoire, as a concept and practice, is poisonous. It stifles the mind and shuts close the space for reevaluation, rediscovery and organic progression.
