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. The style-change was around the mid 1990s. Their albums Era Uma Vez... Ao Vivo (1998), As Quatro Estações (1999), Quatro Estações: O Show (2000) and Sandy & Junior (2001) sold more than a million units and were certified multi-platinum or diamond in Brazil. They had a self-titled weekly television series between 1999 and 2003 on Rede Globo and released the movie Acquaria in 2003; Sandy also starred the soap opera Estrela Guia (Globo) in 2001. Earlier, they had appeared in Renato Aragão movie O Noviço Rebelde, in 1997. Both have experienced solo work: Junior was the drummer of alternative rock band Nove Mil Anjos (which also features former Charlie Brown Jr. member Champignon on bass guitar), and part of an EDM duo called Manimal. Sandy, on the other hand, has a solid solo carreer. In 2002, they were the first national artists to do a paid concert at Maracanã stadium in Rio. The duo announced on 17 April 2007 that an MTV Unplugged album to be recorded in May 2007 would be their final work together, through a video posted on their website addressed to their fans and in a press conference, stating also that their career as a duo would be over at the end of 2007. Their 17 years of career has granted them partnerships with several national and international artists, such as Xuxa, Roberto Carlos, Milton Nascimento, Toquinho, Gilberto Gil, Ivete Sangalo, Andrea Bocelli and Enrique Iglesias, and more than 20 million albums sold around the globe, making them the ninth best selling Brazilian artists of all time. In March 2019, after a 12-year hiatus, the duo announced a new tour to celebrate the 30th anniversary of their first performance together, Nossa História Tour. Starting in July 2019, the siblings commemorated their successful career with their greatest hits in a tour through the largest cities in Brazil.
