The Rio de Janeiro Carnival is undergoing structural and digital transformations. Recent debates have centered on new competition formats designed to reduce costs and increase organizational agility, though some participants argue these changes may compromise artistic quality. Additionally, the rise of social media has altered fan engagement, creating new dynamics regarding the nature of criticism within the samba community.

As preparations move toward the 2027 Carnival, several special group samba schools have finalized or are currently selecting their ‘samba-enredo’ themes. Portela has selected a composition by Wanderley Monteiro and partners to accompany the theme ‘Ao mestre, com carinho’, developed by designer Paulo Barros to honor the legendary composer Monarco. Mangueira has selected the samba ‘Oyá Por Nós’, focusing on the deity Iansã, while Mocidade Independente de Padre Miguel chose a composition centered on Latin American unity. In Maricá, União de Maricá has identified five semifinalist sambas for its debut under the theme ‘Utopia Brasil: Darcy Ribeiro’.

Further developments include Unidos de Padre Miguel releasing its official samba-enredo, ‘Yèyé Omó Ejá – A Coroação das Rainhas das Águas’. Developed by designers Allan Barbosa and Ricardo Hessez, the theme is inspired by Iemanjá and explores connections between the sea and rivers through the deities Iemanjá and Oxum. Additionally, Unidos do Viradouro is scheduled to host a semifinal competition in Niterói on September 12 to select its samba for the theme ‘Griô’, which focuses on West African oral traditions and their influence on Brazilian cultural memory.

To increase accessibility, the Liga Independente das Escolas de Samba do Rio de Janeiro (Liesa) is facilitating live broadcasts of these competitions via the Rio Carnaval TV channel on YouTube to reach a global audience.
