In the history of "O Terço", which has its origins in 1968, are three bands in far-off the 60 - Joint Stock Co., Hot Dog and Os Libertinos, where began the guitarist Sergio Hinds, bassist Cesar de Mercês and drummer Vinícius Cantuária. The group Os Libertino, then formed by the three aforementioned musicians, was an attraction that ruffled domingueiras of Rio de Janeiro. The band was still called Santíssima Trindade. In 1970 or 71, Caesar de Mercês is replaced by Jorge Amiden. Now change the name to O Terço. The set, as I might have guessed, was from Rio de Janeiro, but then would settle down in Sao Paulo.
