Sandy & Junior was a Brazilian pop music duo consisting of sister Sandy Leah Lima (born January 28, 1983) and brother Durval de Lima Junior (born April 11, 1984). They have two albums among the 10 best-sellers ever in Brazil. 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. The style-change was in 1997.
