The first striking element of "Canciones de llanura" is the deep, expressive voice of Ale Oliva. His clear diction ensures that every word is understood upon first listening. The rhythmic structure of the songs also stands out, which makes sense as the album is the work of a multi-instrumentalist whose life revolves around percussion. The album constantly surprises with a wide array of timbres, showcasing a vast palette of sounds. A glance at the technical sheet reveals the variety of instruments used: percussion, wind, string, electric, acoustic, and more.

Additionally, some songs become unforgettable after just one listen. For example, "Valentín" and "Así de frágil" are imbued with a poetic quality that transcends words, blending seamlessly with the music. It's worth noting that several of the album's lyrics are penned by Maia Mónaco, who brings impossible images and unexpected sounds ("buscando tu alma en un malvón," from "Palabras").

Midway through the album, we encounter three songs by other authors, which Oliva makes his own. These include works by none other than Caetano Veloso, Fernando Cabrera, and Eduardo Mateo—an impressive trio to cover. However, Oliva confidently brings fresh perspectives to "London, London" and "Por ejemplo," making them his own.
