This is a whole world of music not a lot of people (at least here in the U.S.) have checked out, or even been exposed to. Thanks to films like Buena Vista Social Club, awareness of this rich vein of musical culture has finally come back into light. Sadly, it's been hidden away for too many years. Blame the Cuban revolution in 1959, blame the U.S. embargo, blame lots of things. Fact is - it's great music and it's gone unnoticed for a very long time. But lots of it, like this track, Profecia, have been sitting in the vaults at RCA and other U.S. labels and haven't been reissued since they first came out. RCA had studios in Havana and recorded a lot of these groups, as did many other labels. Fortunately, much of it is being reissued and discovered and is slowly becoming available.
So if this track appeals - there's a lot more where that came from.
