El mal querer is the second studio album by Spanish singer and songwriter Rosalía. It was released on 2 November 2018 by Columbia Records. The album was written by Rosalía and co-produced with El Guincho on an initial low budget as an independent artist. Presented as experimental and conceptual; a "romantic document that seamlessly links flamenco's characteristic melodrama to the storytelling of modern, woman-flexing R&B", the album follows the anonymous 13th-century Occitan novel Flamenca. It served as the singer's baccalaureate project upon her graduation from Catalonia College of Music with honors.
