I do not consider myself a bachata purist, by any means. Of the newest generation of bachateros, I am no more inclined to support Aventura than I am to support Roman-C. While I commend the NY (read: US based) bachata bands who have found a happy medium between a genre indigenous to their parents' culture, and a/the genre(s) that speak more to their generation or people of their socioeconomic background, I can respect the persepctives of bachateros who prefer unadulterated bachata by the legends such as El Papa de la Bachata or El Mayimbe. Obviously there are justifiable reasons as to why they earned such titles, and their contributions to bachata should never be trivialized or overlooked.
I thought it very interesting that in your reference to the currently popular hybrid styles of bachata, you emphasized the hip hop element. Was that just to give an example of the bachata mixtures that are out there? Most "bicultural" bachata guitarists (Stylez, NV, Nueva Era, Iluxion, J.C) are noticeably more influenced by rock or alternative music. The bands that have remade songs, have remade songs by rock and alternative bands.
