True to his nickname, Sergio Vega was a badass who specialized in narcocorridos—songs of Sinaloa's drug underground, set to a deceptively lively polka beat. On "La Número 20," he spots his lover in a police lineup. "Maniaco y Loco" is almost a love ballad—to a girl who's as "loco" as the singer—while the festive horns and snares on "El Malandrín" suit the tale of a dealer celebrating the good life. Even on the romantic "Quien," Vega's clipped delivery suggests rage beneath the surface.
