A great film, and a great album, which led to the release of many other albums by these fantastic musicians that most of us would never have heard of if not for the film.

But voyager's list leaves out the best part:
Company Segundo (vocals, armónico)
Ibrahim Ferrer (vocals)
Ruben Gonzalez (piano)
and maybe others that I can't think of right now, but those three were leading stars of the movie and the music.

There's a nice clip of Segundo singing and playing the armónico (a guitar/tres hybrid that he invented so that he could play the guitar part and the tres part on the same song) at http://www.youtube.com/watch?v=q61JRKpWg-s, and his duets with Omara Portuondo at http://www.youtube.com/watch?v=YVuHTQm0810 and http://www.youtube.com/watch?v=VRlxgW5yzVU
