However, the original Colmillo Norteño sued them over 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 early 2010, and he founded his own band later that year, recruiting Armando Ramos as guitarist and backing vocalist, Martín López as sousaphonist, and Augusto Guido as drummer. With Muñoz, the group scored the hit songs ' Sueño guajiro' and ' Hotel El Cid' in 2009, among others. 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.īefore establishing Calibre 50, Edén Muñoz had been the accordionist and vocalist in the Norteño-banda group, Colmillo Norteño. Calibre 50 ( Spanish pronunciation: ) is a Regional Mexican band founded in the city of Mazatlán, Sinaloa in 2010.
