****Since The Frogman says the regime frowns on Jazz, there might not be that much NEW, to discover. Except the expatriates.****
To put it in perspective: it is illegal in Cuba to listen to American radio stations. Cubans can tune in to Miami based radio stations a mere 90 miles away, but they have to do it in secret and risk repercussions if caught. Now, rest assured, there is some jazz (real jazz, not Latin jazz) being played in Cuba, but you won't find it in the clubs and certainly not on youtube; big no-no. As far as Latin-jazz goes there is plenty of it there of the type that we hear here and has been posted; but, that is not the problem. Some of the expatriates left Cuba because they wanted to play JAZZ; not Latin-jazz and not Latin-jazz that was "sanctioned" by the government. Note that the tune being played and sung by the bar band in your clip (yes, that is in Cuba) is a Bossa-nova; I doubt that "It Don't Mean A Thing If....." is on their song list.
