I'm listening to Starry Hazy Pie and that is some monster zouk playing, in fact, I find all the instrumental and vocal work impressive. Thanks for the heads up. I can't really think of any new artists that parallel these two but you might like Solas, Malinky and Lothlorien. Also there is a fairly recent recording by Corey Purcell called Flying Solo you might be interested in with more good zouk (and other instruments played by Purcell) and singing.
