The art of Flamenco is rooted in Andalucia, specifically in the south west in and around Sevilla and Cadiz. It is thought that it came to Spain via the Moors or possibly the Sephardic Jews or maybe because the Emperor Charles the Fifth used Flemish body guards who were famous for their exuberant Burgundian behaviour. In those days the gypsy music was much heavier than the Castillian songs, they called it ‘flamenco’, the name also means Flemish. It is probably a combination of all of these factors and many more.
When I first went to live in Madrid many years ago I discovered that the flamenco dance form has its roots in Rajasthan in India where one of the traditional dance forms is called Kathak.
In recent years many artists in Spain have been rediscovering the origins of their music and dance and have been collaborating with Indian artists and musicians to create a new fusion of the two traditions.
(I had hoped to include video from Prashant Shah and his Kathak/Flamenco fusion but the sound quality was very poor so it can stay hidden in YouTube.)
