In order to promote the album, the label stated from
Miami that "
Calambre is the type of signature album many artists spend a lifetime pursuing. Nathy Peluso’s grand vision has been achieved in this work that captures lightning in a bottle and raises the bar for musical excellence". Meanwhile, Jesús García Serrano from
Mondo Sonoro gave the album a seven out of ten defending that "there is no doubt about the talent and versatility of Nathy Peluso; a voice with abundant power, that comes to give a breath of fresh air to Latin pop, fusing urban sounds with classic genres. His rogue lyrics and pose are another story, the same they empower you that make you put your hands to your head". García Serrano also named
Calambre the 33rd best album made-in-Spain of 2020. Online magazine
Remezcla stated that "the record is in-your-face and relentless, which seems to be exactly her goal".
Billboard said that
Calambre is "a box full of surprises, showcasing Peluso’s vocal and rhythmic versatility". Conversely, Peluso has been accused of
cultural appropriation by some Internet publications, due to her use of
Caribbean and
African American symbology. Peluso is from Argentina but has lived in Spain since her early teenage years. Some accused Peluso of blackfishing and trying to copy American rapper
Hurricane G. Many compared Peluso's situation with the one Spanish songstress
Rosalía suffered after releasing her sophomore album
El Mal Querer, which combined flamenco music with modern urban sounds. Rosalía was also accused of appropriating the culture of
Romani people and
Andalusians although being
Catalan. ==Track listing==
