Carolina Mendonça and Catalina Insignares met in 2014 and, since then, they have been collaborating and maintaining a very close complicity in different ways of working together. In 2015, Catalina was the dramaturg of Carolina's piece Falling where horizontal bodies sink into deeper layers of the earth. From 2015 to 2016 the dialogue with Carolina was crucial for the development of the piece us as a useless duet, in which Catalina investigated how dancing with someone else's fragilities generate an encounter. In 2017, they performed an eight-hour nocturnal reading directed at sleeping bodies and titled Useless land. In 2018 they created and performed the piece Pulp - History as a warm wet place, an intuitive archeology that digests the remains of the XVII-XVIII centuries, together with Rodrigo Andreolli, Ida Daniel and Zuzana Zabkova. In 2020 and 2021 they were dedicated to deepening the landscapes with the dead in the research project Ese muerto se lo cargo yo and they established a close conversation with the sirens, seeking to listen to these female monsters whose lethal weapon is their voices.
