Originally known as Grupo Pesado, the norteño group Pesado was founded by frontman/accordionist and Pepe Elizondo (bajo sexto, vocals) in 1993 in Nuevo Leon, Mexico. They debuted with the album Ayudame a Olvidar, released by MCM. Llego el Amor followed in 1994, soon achieving gold status.

Los Invasores de Nuevo León is a Mexican norteño group founded in 1980. They have been considered the greatest school of modern norteño groups and are one of the great references of this musical genre. Their hits include: "Laurita Garza", "Clave 7", "Ni Dada La Quiero", "La Costumbre", "Bajo Mil Llaves", " What a Woman's Value", "Aguanta Corazón", "My New House", "La Vieja Banca" and "A Mi Que Me Quedo", to mention a few.

Los Cardenales de Nuevo León are a Grammy-winning norteño group from Mexico whose bajo sexto and accordion-driven sound has influenced hundreds of succeeding groups in the genre. They emerged from their native Monterrey in 1982, playing social events. Their self-titled debut album was issued the same year and received enough airplay and regional popularity that the band was able to tour extensively in the region.
