I donĀ“t know Tejano. I know that Tex-Mex is a crossover ( [img]i/expressions/face-icon-small-smile.gif[/img] tks SS) from a mexican music ("tropical"
and some texan, similar to country. Maybe it's that one but I really don't know. Selena sang Tex-Mex, in fact she was "La Reyna del Tex-Mex", The Tex-Mex Queen, very popular in the States, mainly in Texas; Jennifer López made an american movie, in english, performing Selena, about five years ago (1997?). Selena was murdered by a female fan about 1994.
Wait! I just read this:
<<
Selena In life, she was the queen of Tejano music >>
LOL. It seems Tex-Mex and Tejano is the same.
