Thom Jurek from
AllMusic gave the album four out of five stars, writing that "it reflects Laferte's particular gifts as a songwriter capable of juxtaposing conflicting, even contradictory emotions and psychological states as well as imbuing physical landscapes and personal interactions, no matter how brief and/or casual, with profound implications", he also commented that "though a 180-degree turn from the
Mexican regional music employed on
Seis,
1940 Carmen is every bit its equal in creativity, emotional depth, and execution". Rodrigo Derbez from
Indie Rocks! gave the album a seven out of ten, writing that while it has high points like "Supermercado" and "A Crying Diamond", the album was not as innovative or fresh as
Seis, he finished the review with "
1940 Carmen is an experience that feels well prepared, much more with a commercial intention than an artistic one, although it doesn't mean that there isn't any heart in this album either, it just feels so clean it's sterile". ==Track listing==
