Korzus is a Brazilian thrash metal band, formed in 1983 in São Paulo. They are one of the first bands of the Brazilian thrash metalscene, along with bands like Sarcófago and Sepultura. Their first release was issued in the seminal metal compilation called SP Metalon Baratos Afins label back in 1985.
They changed the lineup a lot of times since the birth of the band, but three members, Marcello Pompeu (on vocals), Silvio Golfetti (on guitars) and Dick (on bass guitar) remained. The classic lineup of the band (1988–1992) was Marcello Pompeu (vocals), Silvio Golfetti (guitars), Marcelo Nicastro (guitars), Dick (bass) and Roberto Betão Sileci (drums, replacing Zema who committed suicide in 1987).
Lacking the funds to record a studio album, their debut album, which was released in 1986 consisted of a collection of live recordings. A year later they released their first studio album called Sonho Maníaco.
Around that time, Silvio Golfetti played guitars for the L.A. speed metal band Agent Steel for a short time in 1987, because he was a friend of John Cyriis, vocalist of Agent Steel and born in Brazil. He temporarily played guitars for Sepultura at the time when Andreas Kisser was unable to play due to an arm injury.
In 1989, they changed their sound a little, going more in a direction of Bay Area thrash, and released the EP Pay For Your Lies, featuring a cover of Black Sabbath’s “Under the Sun/Every Day Comes and Goes”. During that period Korzus became a major metal band in Brazil; they even struck a friendship with their idol, Formula One racer Ayrton Senna.
