One of my favourite flamenco dancers is Israel Galvan. Galvan 'is a dancer ahead of his time, as no one has ever danced this way' says El Pais: 'nothing he does is orthodox, but you can't question his flamencura (flamenco attitude)', and it's a fair description.
His poses, the angle of his arms, his footwork are different from your traditional flamenco, but at the same time they are not imports from other forms of dance: they are still flamenco.
