Does anyone know much about Latin American Reggae?
 

I am curious to know about what Latin Reggae bands people are listening to. Preferrably looking for afro-caribbean groups from Central America. Nicaragua, Costa Rica, Guatemala, etc...

You will find very few Afro Caribbean artists within those countries. Most of the bands in Central and South America are predominantly White but if you still wish to checkout some bands:

Ponto De Equilibrio
Los Cafres
Natiruts
Gondwana
