La vida era más corta draws from significant collaborations, including artists like Trueno, Soledad, Akriila, Radamel, Cuti, and Roberto Carabajal, as well as featuring contributions from Silvio Rodríguez and an unreleased recording by Mercedes Sosa in the song Jangadero. The vocal arrangements by Agarrate Catalina also enhance several tracks. The album was preceded by the single Bajo de la piel, released on September 4, 2025, which marked the beginning of this new sonic phase and was filmed in Santiago del Estero. Other tracks such as Niño and Recordé also stood out as central highlights of the release, offering profound lyrics about human existence.
The album’s production was primarily led by Tatool, who served as artistic director, and Santi Alvarado, contributing varied instrumentation including piano, charango, electric guitar, and synthesizers. Milo J was actively involved in composition and production, describing the project as a faithful communication of his soul and that of the "Argentine he summoned", understanding folklore as a deep connection. The fusion of traditional instruments like bandoneons and charangos with synthesizers and trap beats seeks to reinterpret popular traditions from a contemporary perspective. Specialized critics, including outlets like Rolling Stone and Indie Hoy, praised the work’s ambition and its ability to blend the popular with the urban, though some comments noted the boldness and potential irregularity of this genre mix.
