The band began in 1995 when two friends, Tito Fuentes (guitar) and Micky "Chicho" Huidobro (bass), started playing together. Javier de la "J" Cueva and Iván Jared "La Quesadillera" Moreno joined them in September of that year, becoming the first line up for the band. Moreno would eventually leave and be replaced by Randy Ebright, the only American member of the band, in October 1995. In February 1996, de la Cueva would also leave. He was replaced by Paco Ayala, establishing the four-member lineup that has remained consistent over the years.
