Contrabando y traición, “smuggling and betrayal,” is the title song of a Los Tigres del Norte album, written by Ángel González. Sopitas dates the album to 1974, and Posta to 1973. The song tells of Emilio Varela and Camelia la Texana, a smuggling couple. Emilio wants to leave Camelia for his true love in San Francisco. Feeling betrayed, Camelia kills him and flees with the money.
Sopitas calls it one of the most important songs of the group’s career, a song that gave “un nuevo auge a los corridos mexicanos” (a new boom to Mexican corridos).
