If you watched the PBS special of "Latin Music USA" you must have seen the video snippet below. This particular section had a particular effect on me when I watched it. It is Rubén Blades and Willie Colón rehearsing one of Blades first songs with Fania Records called "El Cazanguero". It was great to see a young Rubén Blades singing with amazingly clear vocals and eloquent lyrics while Colón was directing the band. For those who haven't seen the documentary - hopefully this video will influence you to watch it. This is a prime example of artists having truly mastered their craft and created something that withstands the test of time. The classics never die.
