[3] To promote the group locally, Residente directed and edited the video for "Se Vale Tó-Tó" with the help of his cousin, which was filmed on a relatively small budget of US$14,000.

[4] The duo gained recognition for their song "Querido FBI", which responded to the killing of Filiberto Ojeda Ríos, a key figure for the Puerto Rican independence movement.

[5] Shortly after, the duo collaborated with Julio Voltio on the single "Chulin Culin Chunfly", which reached number eight on the Billboard Hot Latin Songs chart, creating more buzz for the group.

[8] Anthony Colombo of Billboard noted that the album contains influences "that range from formal conservatory training to street music, animation, and Dadaism".

"[5] On the album, Residente wished to address a diverse array of subjects as opposed to simply discussing politics, which he felt would be "a bore".

[6] Nuria Net, managing editor at Fusion, described Residente's lyrical style by explaining, "Calle 13 rapped about the female body, the nalgas, the curves, the bodily fluids ...

[11] The song's title is a play on words, substituting "to-to", a variation on the Puerto Rican slang term for a vagina ("toto"), for "todo" (all).

[4] The first interlude, "Intel-lú-Ayala", humorously discusses "residents" and "visitors" to Puerto Rico, using the stage names of the two band members to deride colonialism from Spain and the United States on the island.

"[14] The song "Pi-Di-Di-Di" mocks rapper P. Diddy, who had come to Puerto Rico earlier to scout out new musicians, and Residente felt that he was exploiting the island.

"[23] He described Visitante's beats as "inventive", enjoying the record's deviation from reggaeton's "industry-standard trademark of Luny Tunes and that production team's assembly line of bandwagon-jumping imitators.

"[23] Nate Chinen of The New York Times called Residente a "lean and literate rapper" and the album "an intelligent effort, and not just by reggaetón standards.

"[24] Jasmine Garsd of National Public Radio praised Residente's lyrics, describing him as "foul-mouthed and self-deprecating, but undeniably talented" and "as funny as [he is] gross".
