Silvey's influence brought new sounds and recording techniques to this album and helped set it apart from Prográmaton.

[10] Before the release of Aztlán, on 18 April 2018, Zoé held a surprise concert at Glorieta de los Insurgentes in Mexico City, where they performed songs from the album.

[13] The album is named after Aztlán, the mythical ancestral homeland of the Aztec people, and according to Larregui, it was chosen out of pride for their Mexican culture.

"[5] The album cover features an original oil painting by Larregui,[14] presumably depicting the departure of the Aztecs from Aztlán before founding the city of Tenochtitlan in the present day valley of Mexico.

[16] The band released "No hay mal que no dure" and its video on 15 November 2018 as the album's third and final single.
