They each have a head, two arms and two legs, and yet it sometimes seems like they share one body! Siamese twins? Mirror effect? Elda Haksever and Marthe Mosser invent a language where humour competes with the bizarre. Birds of a feather flock together, as the saying goes, and this duo play with the concept, getting to the very heart of the matter. Elda and Marthe dance, sway, freeze, stick together, cling to each other, coincide, merge together, lose themselves and come to resemble each other, with an extraordinary sense of timing that will attract all passers-by, from the youngest to the oldest!
