Los Tigres del Norte formed in Rosa Morada, Mocorito, Sinaloa, Mexico, in the late 1960s by brothers Jorge Hernández (accordion, vocals), Hernán Hernández (bass, vocals), Eduardo Hernández (accordion, saxophone, bajo sexto, vocals), Luis Hernández (bajo sexto, vocals), and cousin Óscar Lara (drums). The group relocated to San Jose, California, where they signed with Fama Records in the early 1970s and transitioned from acoustic to electric instrumentation, incorporating elements of boleros, cumbias, rock, and waltzes into their norteño style. Their 1974 hit 'Contrabando y Traición' established the narcocorrido subgenre and propelled their career, leading to over 60 albums, sales exceeding 32 million units, multiple Grammy Awards, and films. They have toured extensively in Latin America, Europe, and Asia. The band performs high-energy live shows featuring accordion-driven corridos that address themes of migration, border life, and social issues, drawing large audiences in Mexican-American communities.
