Aidalai is an album by pop group Mecano. It was released in 1991 and produced by the group. Its launch was in the middle of rumors of the separation of the group due to differences between Nacho Cano and José María Cano. It was their third release with Ariola Records. The title refers to a game word: ¡Ay Dalai!, meaning in English something like Oh Dalai!. 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. "Tú" (You), a sensitive song by José María Cano, is also included. José María Cano's song "Una rosa es una rosa" (A rose is a rose) was inspired by the famous sentences of the writer Gertrude Stein: Rose is a rose is a rose is a rose and the video won in the category of "Best National Video of the Year" in the Ondas Awards and the Lo Nuestro Award for Video of the Year.
