Ácido Argentino is the second studio album by Argentine thrash metal band Hermética, released in 1991 by Trípoli Discos.

During the year they played with Todos Tus Muertos, Pobres Pibes, Nepal, Militia, Devastación, Rapier, Resistencia Nativa, etc.

Strunz had only six hours to record all the drums, and Iorio had to finish some lyrics in the studios.

[5] The cover features Uncle Sam abousing of a woman with a phrygian cap, police attacking the Mothers of Plaza de Mayo, ravens around a destroyed church, and other images lifted from the lyrics of the songs.

"Vientos de Poder", with music by Romano, has twisted riffs, while he considered that "Memoria de Siglos" may be monotonous and even boring if played as an instrumental song; the reason of its popularity is in its lyrics.

[5] The magazine Rolling Stone lists it as the most essential album of Argentine heavy metal.
