Blues Etílicos is a Brazilian blues band created in Rio de Janeiro in 1985 by the harmonica player Flávio Guimarães , bassist Cláudio Bedran and guitarist Otávio Rocha and, a few months after their debut, incorporated singer and guitarist Greg Wilson and drummer Gil Eduardo . In 1987, the band recorded their first LP, under the independent label Satisfaction Discos. Soon after, they were hired by the label Eldorado, launching Água Mineral in 89, San Ho Zay in 1990 and IV in 91. San Ho Zay reaches the mark of 35,000 copies sold, being the best selling album by a Brazilian blues band in all times.
In 1989, the band had a wide projection through the first International Blues Festival, in the city of Ribeirão Preto, opening the festival on the same night as Buddy Guy. The festival was a game changer for the genre in Brazil and several national bands emerged influenced by the sound of the Ethical Blues. During this period, Blues Etílicos had several special programs on TV Cultura, Rede Manchete and MTV, in addition to having their songs widely played on radio stations across the country.
