I recently came across a band I really like, called Cultura Profetica. They are a roots reggae/world music band from San Juan, Puerto Rico.
The first song I heard by them, that made me have to look them up and listen to more, is called Un Deseo (A Wish). It has a really sweet, lilting groove, with a jazz influence.
Their vocals are very nice, both the lead and the harmonies.
So I have included them among my favorites.
