Brazilian thrash metal is a regional scene of thrash metal music that originated during the 1980s in Brazil. Along with Bay Area thrash metal, and Teutonic thrash metal, it was one of the major scenes of thrash metal in the 1980s. Though not as large or well known as the North American or European thrash movements, it is still a pivotal point in heavy metal, as it bridges the gap between the thrash of the mid-80s and the death metal scene later in the decade, as well as part of the first-wave black metal.

During the early eighties, bands from the U.S., Germany and Canada, such as Metallica, SLAYER (USA), Destruction, Kreator (Germany), Voivod and Exciter (Canada) appeared. At the same time, Brazil had a growing scene as well, and was also influenced by the same music.
The European and North American heavy metal and hardcore have been a great influence on all Brazilian bands, but the first thrash metal (or speed metal) album released officially in Brazil was a split album “Ultimatum”in 1984 between two bands – Dorsal Atlântica and Metalmorphose.  There were three regions where the Brazilian THRASH METAL was originated (Belo Horizonte, São Paulo and Rio de Janeiro). The most prominent of the three scenes, was from the city, Belo Horizonte, where Sepultura came from. Find out more about top 10 Brazilian thrash metal bands
