Hailing from the backwater Amazonian city of Belém, where she still lives in her childhood home, Amarantos is the first tecnobrega artist to gain widespread national fame. The genre was born in Northern Brazil about a decade ago, as a fusion of “cheesy” pop and cool techno. In the video for “Xirley,” the bodacious Amarantos struts through a kind of Groundhog Day of upward mobility: first entering her apartment in street clothing and, by the endof the song, sashaying down a catwalk in her living room wearing an electrified Carnival getup. She recently visited New York, where she performed in Central Park and toured the city trailed by a documentary-film crew. Expect to hear much more from her next year: She recorded the official theme song for the 2014 World Cup.
