After three decades, 38 albums and over 12 million copies sold, La Mafia is back with their new single "Que No Quede Huella / Como Me Duele Amor" Oscar de la Rosa and Armando Lichtenberger Jr., leaders of the Mafia, started promoting their new single "Que No Quede Huella / Como Me Duele Amor", with the participation of guest artist Bronco. La Mafia’s returning to the studio could not be more spectacular than with this new single, which is an innovative project titled “Unicos” which has as a special guest Bronco. "Que No Quede Huella" is their most representative theme and one of the biggest successes of the Monterrey based group, but this time performed by La Mafia, in their unique style, while the hit "Como Me Duele Amor", one of La Mafia’s biggest hits now interpreted by Bronco, but in their own unique way. Definitely a great idea by La Mafia lead vocalist Oscar De La Rosa who’s idea gives a fresh take on two classics.
