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 issues such as absence, memory, history and politics. The use of archive material, their own and others', is one of their main fields of experimentation. Their works has been programmed and awarded at festivals (Mar de Plata, DocLisboa, É tudo Verdade, EMAF, Documenta Madrid, Zinebi, Punto de Vista, FICX) and renowned international art centres (Kunstmuseum Bonn, MNCARS, CCCB, Arteleku).

Their first film, the feature documentary Pepe el andaluz (2012), deals with a family story to talk about wounds, secrets and love. For over a decade they have been conducting 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 in Spain. The result of this research is the short film Descartes (2021) and his latest feature film, Caja de Resistencia (2024), a fabulation of the filmmaker's unfinished projects.
