Tren Loco is an Argentine heavy metal band formed in the suburban town of Grand Bourg, in Buenos Aires Province. Their lyrics relate social issues, like "Clase trabajadora" (Working class), "Fuera de la Ley" (Outlaw) and "Lucila"; others are about political issues, such as "Pampa del Infierno" (Hell's Land) and "Nos vemos en Cutral-Co" (See you at Cutral-Co). They also write about personal matters: "Endemoniado" (Possessed), "No me importa" (I do not care) and "A ultranza" (To the end). The group's name is inspired by the classic Ozzy Osbourne song: Crazy Train.^[2]

The bass player Gustavo Zavala created a new band in 1990, after the breakup of his previous band, Apocalipsis. He called the guitarist Rubén El Turco Atala, the drummer El Pollo Fuentes and the singer Gabriel Marian. The songs composed by this line-up were published in the album Apocalipsis in 1985.^[3] A month later, the singer Carlos Cabral leaves the band Dhak and joins Tren Loco, at the same time Mauricio Pregler joins as the second guitarist and Sergio Rojas as keyboardist.

In early 1991, they recorded their first demo at Sonovision studios, in Buenos Aires, with Álvaro Villagra as the producer. That same year, on June 23, they performed a show at Halley Discothèque and started the competition for the Yamaha Band Explosion.

They finally reached to the finals in Tokyo, Japan, where they played at the Budokan Stadium, competing with bands from Germany, Spain, United States, France and England.
