Elena Asins (Madrid, 1940 - Azpíroz, Navarra, 2015) is one of the most radical and rigorous artists in the Spanish art scene. A renovator of plastic language, Asins combines the constructive tradition of twentieth-century avant-garde with computation and information theory, being considered one of the pioneers of computer-assisted art in Spain. A brilliant artist, provocative in silence, who builds from structure, from mathematical norm and logic, a work that generates itself to become, at times, almost invisible.Through, fundamentally, the works bequeathed by the artist to the Museo Nacional Centro de Arte Reina Sofía, this exhibition proposes a journey through the persistent investigations carried out by the artist and their plastic results: a final work of apparent simplicity in its calculations, but linguistically hermetic. True to herself and the result of her renunciation of color, Elena Asins's works are read first through the word and then through structure and line. Never forgetting the tempo: an internal music that runs through all her artistic production, sequencing it. Asins has resorted in her works to a wide range of formats and media from concrete poetry to video, passing through drawing, sculpture or installation, always characterized by compositional rigor and formal refinement.Linked to some of the most innovative projects in the recent history of Spanish art, such as the Cooperative of Artistic and Craft Production or the Computing Center of the Complutense University of Madrid, we highlight the encounter there with Eusebio Sempere and Abel Martín, their friendship and the coincidence of their investigations. And we will show for the first time a fundamental work by Elena Asins: the Songs of Orpheus, a series of visual poems dated 1970 and preserved by Eusebio Sempere that have become one of the most important pieces in the history of Spanish experimental poetry.
