Within LUX, some pieces stand out for their particularity. "Sexo, violencia y llantas" opens the album with a sonic statement that invites reflection on its content. "Reliquia" and "Divinize" are other compositions that are part of the 18-track offering in its physical editions, while digital versions feature 15 songs. The artist, who began her musical training at age 10 and specialized in flamenco at the Escola Superior de Música de Catalunya, has demonstrated throughout her career an ability to fuse genres, from the flamenco she studied with Raül Refree on her first album Los Ángeles, to urban music and trap.
The conception of LUX is described as a creative process that emerged from "a place of purity," seeking a genuine connection with her art. The promotional campaign included a live appearance in Madrid, where Rosalía walked the streets surrounded by her fans, transforming the album announcement into a spectacle. This focus on experience and direct connection with the audience is something that has characterized her trajectory since its beginnings, consolidating her presence in the music scene.
