From their website "This group, which emerged on May 11, 1933 in Cadereyta and later became a representative icon of Santiago , is perhaps the longest not only in Nuevo León , but in the region. 　　Its founding members were: Don Pedro Mier and Mier and their children , Nicandro and Jaime Mier Pérez , Wenceslado Moreno . In 1944 Don Gudelio Cavazos and Don Fidencio Almaguer are integrated, giving the group a very special sound apart from the flute, the violin and with the sixth bass, saxophone and double bass."
