The duo was officially formed in 1993 by Erk Aicrag (Erik Garcia), who sings the lyrics and vocals, and Racso Agroyam (Oscar Mayorga), who does programming, but both cousins had been experimenting with electronic music, mixing industrial and EBM, since they were fifteen years old. Their music can be described as electro-industrial. Given the influence of varying currents of electronic music (mainly Skinny Puppy) they began their trajectory in 1989 in a project called "Niñera Degenerada". Their lyrics are both in Spanish as well as English. The Spanish word hocico means snout, and is used in Mexico as a disrespectful way to describe someone's comments coming out of their mouth.
