Los Tigres del Norte are an internationally successful norteño group from Mexico based in California. Since the late 1960s, this family band has detailed the struggles and triumphs, romances, and heartbreaks of working people, families, immigrants, outlaws, politicians, and farmers. Over more than 70 albums -- including 22 number ones -- they turned norteño, an accordion-based polka music indigenous to Northern Mexico, into commercially viable pop music, infusing the tradition with boleros, cumbias, rock rhythms, waltzes, and sound effects.
