Known for his interactive installations and for being the founder of the mythical theater company "La Fura dels Baus", Marcelí Antúnez is one of the figures of international action art. Performance, drawing and technological and scientific research merge in his Transdisciplinary cosmology to reflect on universal concerns: the body, food, sex and death. An imaginary of its own that in recent years has been even more open to community work. This monograph has been shot in the Barcelona studio of Marcel · Lí and different locations where the artist's latest exhibition projects were developed. In his study, he gave us a detailed interview in which he delves into his biography. From a young age, he was interested in both Fine Arts and biology and stood out for his talent for drawing. “For me, thinking is drawing, or drawing is thinking” -the artist tells us. His immersion in the alternative Barcelona scene of the 80s was key to developing a fluid way of conceiving creation in relation to the arts of the body . In the 80s, Barcelona was a cultural hotspot and Marcel·lí opted for the interrelation of several disciplines: "Theater, performance, opera, dance, are meeting places for the arts" - he tells us. a powerful theatrical scene that understood art as a way of life. In that spirit, joined by the transgressive influence of punk, Antúnez conceived La Fura dels Baus (1979-1989) first, and later: Los Rinos (1985-1992), one of the most explosive and influential performance collectives in the world. In the 90's, Marcel·lí Antúnez is also, already alone, one of the promoters of technological performance and his original interactive actions and installations have made him a figure in the post-humanist performative scene international.
