Overdose is a metal pioneer band from the Brazilian region of Minas Gerais. Progress of Decadence, their most famous effort and also their most exotic album was released in 1993 through the U.S. label Futurist. At those times the band developed a consistent mixture between Brazilian folkloric drums, whistles and thrash metal. His lyrics were based upon social problems and desolated landscapes of poverty into the Capitalistic societies.

Soon afterwards, the band headed for a world tour, achieving huge success specially in the US. That success leaded the recording of Scars in 1995, more focused in thrash metal mastery than their earlier album.

In 1985, the very beginnings of the band, they divided with Sepultura the most famous split album of Brazilian metal, also the first LP released by the label Cogumelo Records. "Século XX" assured countrywide recognition to the band. Though their first LP was Conscience in 1987, followed for the album You Re Really Big released in 1989 and featuring a melodic Heavy Metal sound which became of wide acceptance. In 1990 Overdose recorded Addicted to Reality conceiving their Thrash Metal sound. At 1992 the band released Circus of Death which was the base of various later recordings.
