Love and hate. Apparently two opposing poles, two conflicting emotions. Or perhaps more likely a binary construction, a simplification of real feelings? The performance «I love you/I hate you» starts from this duality in order to understand it, question it and blur it. Based on Gilles Deleuze's concepts of difference and repetition and Judith Butler's theory of performativity - a priori contradictory - the Duet 2.26 performance goes from love, which cannot be understood without difference, to hate, which cannot be understood without repetition. This show is conceived in the form of a double spiral of repetitions in which the loops of each spiral are increasingly closer together; in which it is clear from the very first moment that exact repetition - or, to put it more precisely, replication - is not possible no matter how much effort is put into it. Similarly to the borders between love and hate, the borders between original and copy are blurred at the moment of performance. Beyond understanding repetition as a replica of a pre-existing and immovable original, it has to be understood as a motor of creation through difference, however small it may be. The performance has an interdisciplinary approach, combining music, theatre, lighting and video, and allows the concepts of repetition and difference to be explored from different perspectives, thus representing a complex and fragmentary reality. The fragments, which can be understood as altered repetitions that form a mosaic, are connected to each other through video projections that refer to the concepts of repetition and difference.
