Led by singer, songwriter, and accordionist Sergio Sanchez Ayon, Los Titanes de Durango is really a grupero foursome that melds banda, norteño, and duranguense stylings to get a sound which has transcended the group’s own house bottom in Culiacán, Sinaloa, Mexico, and spread towards the American Southwest and beyond. The quartet obtained its first Best 40 strike, “Un Borracho,” in 2008.
