Source-derived summary

Calema are a Portugal-based music duo from São Tomé and Príncipe formed by the two brothers António Mendes Ferreira (born 5 April 1992) and Fradique Mendes Ferreira (born 19 March 1987). The name of the duo refers to the special undulation on the African coast. Calema is one of the most successful musical acts of the 2020s in Portugal.

Early life

They started singing together at a very young age as they took music as a hobby. In 2008, after being crowned Absolute Winners in the 1st National Santomean Music Competitions, held in their homeland, they came to Portugal to pursue their professional degrees in the music industry. Fradique pursued a degree in Multimedia in Évora and António, a degree in Video Production in Lisbon. In 2011 they went to France with their family and kept on doing music, as they created their cover channel on YouTube.

Career

While they were in France, they kept entering talent shows, winning one of them called "Luso artist". Three years later, Anselmo Ralph noticed them and made them enter the Portuguese music scene. Later on, they produced the album A Nossa Vez – or simply A.N.V – which included the single "A Nossa Vez".

Editorial summary

This brief starts where responsible research should: with the source description of “Calema” as são-Toméan musical duo. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current lead gives the account dated anchors—1992, 1987, 2008, 2011—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where Calema, São-Toméan and musical can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as são-Toméan musical duo. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 27, 2026. The linked authority identifier is Q61749208. VIAF identifies the subject as 3173169829173237320006. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1992, 1987, 2008 and 2011.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
