The pre-production stages for "Tajo Abierto" began at the end of 2012, when Valenzuela began composing new material. Unlike her previous albums which were produced and recorded in Santiago, Chile, she relocated to Los Angeles, California to work on demos at her home and met with producers in early 2013. This is her first album largely recorded outside of Chile. Valenzuela recorded the album with the help of four producers: Vicente Sanfuentes, Jesse Rogg, Dave Sitek and Áureo Baqueiro. Musically, the album is a departure from Valenzuela's earlier jazz and folk influenced sound. She remarked that the writing and production of the album allowed her to explore other genres and leave her comfort zone. She wrote and composed 25 songs for the album and chose 11 for the final track listing. The album was recorded in various home recording studios in Los Angeles, with the exception of one song, "Cuequita del corazón", which Valenzuela recorded in Santiago, Chile with her band and a string quartet at Estudios del Sur. After writing "Cuequita del corazón", Valenzuela remarked that she knew she had to record it immediately with her band in Santiago.
