Samba
Although samba exists throughout Brazil – especially in the states of Bahia, Maranhão, Minas Gerais, and São Paulo – in the form of various popular rhythms and dances that originated from the regional batuque of the eastern Brazilian state of Bahia, a music form from Cape Verde, samba is frequently identified as a musical expression of urban Rio de Janeiro, where it developed during the first years of the 20th century. Early styles of samba - and specifically samba de roda - are traced back to the Recôncavo region of Bahia during the 17th century, and the informal dancing following a candomblé ceremony. It was in Rio de Janeiro that the dance practiced by former slaves who migrated from Bahia came into contact with and incorporated other genres played in the city (such as the polka, the maxixe, the lundu, and the xote), acquiring a completely unique character and creating the "samba carioca urbana" (samba school) and "carnavalesco" (Carnaval school director). Samba schools are large organizations of up to 5,000 people which compete annually in the Carnival with thematic floats, elaborate costumes, and original music.
Samba
Also in the 1960s came the samba funk. The samba-funk emerged at the end of the 1960s with pianist Dom Salvador and his group, which merged the samba with American funk, which was then newly arrived in the Brazil. With the departure of Dom Salvador to the United States, the band broke up, but at the beginning of the 1970s, some ex-members, including Luiz Carlos, José Carlos Barroso, and Oberdan joined Christovao Bastos, Jamil Joanes, Cláudio Stevenson and Lúcio da Silva to form Banda Black Rio. The new group has deepened the work of Don Salvador in the double mixture of the bar with the Brazilian samba funk of the American Quaternary, based on the dynamics of implementation, driven by drums and bass. Even after the Banda Black Rio in the 1980s, British disc jockeys began to play the group's work. It was rediscovered throughout Europe, but mainly in UK and Germany.
