I'm more a fan of Augustin Lara than Lafourcade and I think she's done a wonderful job of adapting his music to her quirky style and still showing some respect. I won't say these are updated arrangements as some of them sound very vintage. I'm just nuts for the song she does with Miguel Bose. It's also nice to hear other Latin pop stars sing with her, for better and worse.
She obvious loves the music and it makes me want to keep an open mind about her future projects.
Try and buy the version with the DVD. I think some of the music is even better on this "live" performance, especially Lila Downs singing with her on La Fujitiva.
