Query: AN UNFORGETTABLE CONCERT

Rocio Durcal is loved not only by Spain and Mexico but from all over the world. excellent concert, her voice is beautiful, she sang her heart out and the music was astounding. Although the sound isnt that great, its lack of remastering when transferring it to dvd. but its good.ITS A MUST HAVE.
