The musical universe of the Amazon region, that includes rhythms brega, tecnobrega and tecnomelody, is mostly ignored by the rest of the country.
Check here for a sample of musicians of the state of Pará. The most popular is Gaby Amarantos, a Valkyrie that is also known as Beyoncé of Pará, but I would like to call your attention to Dona Onete and the instrumental ensembles, such as Orquestra Jovem de Cellos da Amazônia.
