The most recent artist I've gotten into is Mon Laferte. Even though she's huge in Latin America, I was completely oblivious. I like that she hasn't settled into a single style, but rather really likes to train her voice to do new things. Probably the song (and particularly this performance) that gets passed around the most is this one:Mon Laferte - Tu Falta De Querer (En Vivo)
It starts out a bit unassuming, but then she gets to the chorus and belts it out. By the end, you can tell she left it all out there on the stage.
