Cantaor Children
The earliest steps taken by artists such as MoraÃto, La Macanita, Remedios Amaya, Carmelilla Montoya, Antonio de la Malena and Carlos Heredia, who fascinated their relatives, friends and neighbours with their gracefulness and self-assurance from a very young age. They are unique performances that provide some of the keys for understanding the transmisssion of the heritage of flamenco culture.
