[1] Their interest in the industrial and EBM genres led them to begin their musical career in 1989 in a group called Niñera Degenerada.

In certain contexts, "callate el hocico" could be interpreted as, essentially, "shut your fucking mouth," which the band thought described their musical attitude well.

[5] In 1997 the band released their first full CD, Odio Bajo El Alma,[6] on the label Opción Sónica with European distribution through Out Of Line.

[7] The release of Odio Bajo El Alma was well received in Europe and America but caught the Anglo- and Euro-centric scene by surprise, with many unaware that the band's style of electronic music was happening in Mexico.

[2] In 2002, the band released the album Signos De Aberracion[12] (translated: Signs of Aberration), the subject matter of which treated on disturbing events within their social environment at the time.

[7] The band is known for producing an aggressive style of electronic music, which they attribute to their experiences growing up and living in Mexico City.

[20] Hocico has toured extensively over their career with their live shows projecting the same sort of aggressive energy of their musical style, sometimes to the point of physical injury.

[23] In April 2020, Blutengel and Hocico jointly created a track named "Obscured" and released it as a maxi single in preparation for their European "Living the Darkness" tour.
