Jorge Mário da Silva was born in 1970 in Belford Roxo, in the Metropolitan Area of Rio de Janeiro, and from an early age he knew he wanted to be a musician. He worked several jobs from the age of 10 onwards, was a regular at balls and Samba gatherings in Rio, and started out young singing at clubs. He left home at 19 and lived on the streets for a few years, where he had his first contact with theater. Discovered by clarinet player Paulo Moura, he auditioned for a musical and his life changed entirely ever since.
Seu Jorge (a nickname given by drummer and friend Marcelo Yuka) made his first mark as a professional musician in 1998: as a member of band Farofa Carioca, he released the album Moro no Brasil in Portugal, Japan and Brazil.
In 2001 he released his first solo album, Samba Esporte Fino, produced by Mário Caldato and Seu Jorge, and mixed and mastered in Los Angeles by Mário Caldato. In the following year he co-wrote the song Tem espaço na Van, with Ed Motta, and made a Partido Alto-style Samba project named Caatinga de Swing, performing in a night club in the south side of Rio and at Skol Rio.
In 2003 he recorded the album CRU in Itaipava, featuring musical production by the French Jerome Pigeon, and in that same year he co-wrote, with singer Ana Carolina, the songs Beat da Beata and Não fale desse jeito, for her highly successful album, Estampado.
