Sandy e Junior is a Brazilian pop music duo formed by siblings Sandy Leah Lima (born January 28, 1983) and Durval de Lima Junior (or simply Junior Lima) (born April 11, 1984). They have two albums among the best-selling albums of all-time in Brazil. Formed in 1990, Sandy & Junior began by singing children's songs and sertanejo-influenced tracks (their first single, "Maria Chiquinha", is a classic sertanejo song). Once they reached adolescence, they changed their style to pop-influenced songs, mainly ballads and upbeat songs.
