Mezcolanza is a coloquial word for a strange mixture, a mishmash, a hotchpotch, a jumble. There is, I hope, a strange mixture of music on this site. And all of it is a product of the mixing of very diverse cultures. For instance flamenco music and dance is said to have originated at the time when Islamic, Jewish, Castillian and gipsy cultures rubbed up against each other in Andalucia.
Here are some wonderful songs that have their roots in flamenco as well as other genres. The music is variously described as nuevo flamenco, flamencado (to sound cool you shouldn't sound the letter 'd'), flamenquito, flamenco fusión, jip-jop flamenkillo and even flamenco billy.
