O Rappa (Pronounced "U Hah-pah") is a Brazilian reggae/rock band from Rio de Janeiro, Brazil. They combine many styles such as Rock, Reggae, Funk, Hip hop and Samba. O Rappa's songs contain sharp protests against the social problems occurring in Brazil and the members of the band themselves are supporters of numerous social projects.
In 1993, the reggae artist Papa Winnie came to Brazil but he had no band to play shows with him. He immediately picked four people: Nelson Meirelles, Marcelo Lobato, Alexandre Menezes and Marcelo Yuka as the band. After Papa Winnie's shows, the four decided to stay together picking Falcão as the 5th member and vocalist.
