Aidalai songs range from very minimalist ones like "Sentía" (I felt), a kind of bossa nova music in which the voice of singer Ana Torroja is accompanied by only two acoustic guitars and maracas, to others as complex as "Naturaleza muerta" (Still Nature), which has a complex orchestral string arrangement.

However, also on the album are songs typical of the group's techno pop style, like "El fallo positivo" (The positive verdict) about the issue of AIDS, with perhaps one of the best works of vocal arrangements of Nacho Cano, and "Dalai Lama", that narrates the life of the Dalai Lama and the invasion of Tibet by China.

It also includes "El 7 de septiembre" (September 7th), written by Nacho Cano, which won best song of the year in Spain in 1991 and was dedicated to his ex-girlfriend, the writer Coloma Fernández Armero.

It has a length of 56:02 min; it includes 6 tracks in Italian and the rest in Spanish.

Its adaptations were made by Luc Plamondon, D. Burgard, M. Penalva and A. Moreau.
