Cidinho e Doca are part of the Proibidão ("Strongly Prohibited") subgenre of Funk carioca. Most proibidão is illegal to perform or broadcast due to it's lyrics promoting drug gangs and related crimes, and acts within the genre are extremely localized as a result.
Cidinho and Doca are known for their rendition of "Rap das Armas" (English: Rap of Weapons), a 1990s song originally by Junior e Leonardo. This version gained popularity among European electronic DJs, who were experimenting with Brazilian funk remixes throughout the 2000s, earning the song chart spots in Sweden and the Netherlands.
