[8] The album contains a series of duet versions of songs alongside different artists from both Argentina, as well as from other countries such as Mexico, Uruguay, Brazil, Colombia, Spain and Venezuela.

In his review for Cantora 1 he wrote that "contrary to the quintessential Sosa recordings, Cantora is a fairly subdued affair, with most songs whispered against unobtrusive yet tasteful acoustic arrangements by Poppi Spatocco", also commenting that the production "certainly works very well, as it creates an encompassing sonic texture that helps to render the entire album less dissimilar than it may have been".

[12] In the review for Cantora 2 he wrote that both albums as a whole are "a touching, dignified conclusion to a musical legacy that is as enormous as it is precious" while also calling "Canción Para un Niño de la Calle", the collaboration with Puerto Rican rapper Residente, as "the highlight of the entire project".
