The CharroBoys have a talk with their very first mariachi teacher and known mariachi historian William Gradante, aka Dr.G. With a career spanning over 37 years as the first mariachi educator in Fort Worth, Texas, we get into his beginnings in music, his travels around the world with his students, and the beginnings of Sammy and Victor's musical journeys that started in his classroom. We wouldn't even be playing mariachi if it weren't for this man. Blessed.
