Anyone intrested in seeing and hearing something of the variety of folk music in Andalucia should check out the site of the Centro Andaluz de Flamenco (http://caf.cica.es/ - it's in Spanish).

In particlular, this page http://caf.cica.es/mundo_flamenco/flamcd/c/2.htm

has real-time videos and recordings showing many musical forms including fandangos, tanguillas, sevillanas, verdiales etc. It shows something of the variety of instruments used. And, of course, the music is accompanied by the most beautiful, sensuous folk-dancing in the world (IMHO!).

!Vamos a bailar,
A bailar y cantar!
