Munhoz & Mariano and Rionegro & Solimões are Brazilian sertanejo duos prominent in the contemporary country scene. Both pairs originate from Brazil and perform within sertanejo and sertanejo universitário styles, blending traditional Brazilian country themes with pop-influenced arrangements, electric guitar, and polished studio production. Active from the early 2000s into the 2010s and beyond, they are known for melodic vocal harmonies, romantic lyrics, and danceable ballads that appeal to mainstream audiences across Brazil. Their work exemplifies the commercialization and modernization of sertanejo that brought the genre widespread national popularity.
