The Mexican group Banda Los Recoditos were formed in 1989 in Mazatlán, Sinaloa. The original line-up included the well known Sinaloense musician Pancho Barraza. During the history of the band some original members went their separate ways and formed Banda Vuelta De Río which has led to some controversy as to which of the two bands can rightfully claim to be the original with both bands playing hits from the early albums during their live shows. Banda Los Recoditos emerged as the most successful incarnation of the group and now have more than 20 studio albums to their credit including the much acclaimed '¡Ando Bien Pedo!' which went to number one in the US Billboard Latin Charts. With two Latin Grammy nominations to their name the band have become one of the best known exponents of the style known as Bandas Sinoalenses, a genre defined by its reliance on the distinctive 'hermiola' time signatures which uses three beats of equal value to occupy the space of two normal beats.
