Concha Barquero and Alejandro Alvarado (Málaga, 1975) are filmmakers and researchers. Since the early 2000s they have formed a creative tandem operating from Andalusia. Throughout their career they have explored the possibilities of different media, such as cultural television or creative documentaries, in which they have specialised. Their films question themes such as absence, memory, history and politics. The use of archive material, their own and others', is one of their main fields of experimentation. His works have been programmed and awarded at festivals (Mar de Plata, DocLisboa, É tudo Verdade, EMAF, Documenta Madrid, Zinebi, Punto de Vista, FICX) and art centres of international prestige (Kunstmuseum Bonn, MNCARS, CCCB, Arteleku).

Their first film, the feature film Pepe el andaluz (2012), deals with a family story to talk about wounds, secrets and love. For more than a decade they have been carrying out academic and cinematographic research into the work of filmmaker Fernando Ruiz Vergara, director of the documentary Rocío, which was judicially censored in the midst of democracy. The result of this research is the short film Descartes ( 2021) and his latest film, Caja de Resistencia ( 2024), a fabulation of the filmmaker's unfinished projects.
