Chico Buarque's poetics in Construção took a step forward in his critical facet. While he previously fused Bossa Nova with veiled comments on the dictatorship, in this work he is more direct. This is evident in the opening verses of Deus lhe pague, the song that opens the LP, where he sings about basic needs. In Samba de Orly, a collaboration with Toquinho and Vinicius de Moraes, he openly addresses the experience of exile, which led to the song suffering partial censorship. Construção itself is a reflection on the life of a man who works tirelessly until his death. However, the artist's characteristic lyricism remains present in themes such as Olha Maria and Valsinha.
The magazine Realidade, in 1972, described the album as "the best made in the last twenty years in Brazil," highlighting its relevance against imported music and Chico Buarque's role in the national music scene. The song that gives the album its title, Construção, stands out for its innovative structure, employing dodecasyllabic verses and repetitions that create an almost hypnotic rhythm, reinforcing the idea of worker alienation. The participation of guest musicians, such as Tom Jobim on piano and the group MPB-4 on backing vocals, added an additional layer of richness to the work. The album, released by Philips Records, was received with great acclaim from both critics and the public, consolidating itself as a milestone in Brazilian music.
