Buitres was formed after Los Estomagos' dissolution, and it originally had three of its members, Gabriel Peluffo as the lead singer, Gustavo Parodi on guitar and Marcelo Lasso on the drums.

In March 1990, they published their eponymous debut under the Orfeo label which was composed of 13 songs, 4 tracks being covers from other bands.

And the next year they published another album, called "La Bruja" which had mostly original material, except for a Johnny Thunder's cover.

That same year the videoclips from the songs "Calaveratur" and "Del Cardál" (a Eustaquio Sosa cover) were aired on MTV.

In that period of time the first alignment change was made: the drummer, Marcelo Lasso, left the band and was replaced by Irvin Carvallo.
