The music tradition in Tijuana is rich and deep. However, the Nor-tec music and the evolution gives a clearer picture of music evolution than any other. It articulates three well differentiated musical traditions that have been appropriated for decades by the Mexican Northerners. These are the Nortena, banda sinaloense and the Onda grupera.

This background shows that the Mexican/Mexican – American style developed as a hybrid of Mexican, border and European traditions.however, this too kept changing with the norteno and conjunto traditions kept changing with the changing economic conditions of their audience on both sides of the border, as the them migration, racial discrimination, illegal trafficking and inter-genre influences popularized by the US and Mexican media through the 1950s and the 1960s.
