Two favorites that have been heavily in the rotation lately (although I too would never claim expertise) would have to include:
Malingo, Tangos Bajos (heralded as the new voice of Argentine tango and widely refered to as the guy who is "putting the whorehouse back in the tango - he's got a new one out, too, that I haven't picked up yet), and
Marisa Monte, A Great Noise (a classically trained Brazilian opera singer turned sexpot diva, she also has a newer one out that I wasn't as impressed with).
