The name of the band comes from the comparison "with an element that will symbolize the strength and impact that the project has on the lives of the members, as well as those who like the Regional Mexican genre."Ĭalibre 50 first achieved notoriety for their controversial songs, among them corridos. They chose the name by which they are known nowadays: Calibre 50. However, the original Colmillo Norteño sued them for the name, and after a legal dispute Muñoz' band was forced to change their name later in 2010. The name of this new band was "Puro Colmillo Norteño", and they recorded their first album, "Renovar o Morir", under that name, as well as their first single ("El infiernito"). Nevertheless, conflicts with the other members of the band led Muñoz to quit Colmillo Norteño in December 2009, and he founded his own band in 2010, recruiting Armando Ramos as guitarist, Augusto Guido as drummer and Martín López as tuba player. With Muñoz, the group scored the hit songs "Sueño guajiro" and "Hotel El Cid" in 2009, among others.

Contentsīefore founding Calibre 50, Edén Muñoz had been the accordionist and vocalist in the Norteño-banda group, Colmillo Norteño. Their style is Norteño-Banda, a hybrid of Norteño, which uses an electric bass or tololoche for the low notes and replaces it with a sousaphone (tuba), which is typically used in Banda for the bass notes. Calibre 50 is a Regional Mexican band founded in the city of Mazatlán, Sinaloa in 2010.
