Synthetica was released last week and is pretty interesting. Like the name implies, it leans fairly heavy at times on synthesizers...which works in a way since her voice can easily trend towards the 80s when she wants...think Blondie, in a good way. Her voice is really fantastic!
So, while the album is rather short at 11 songs, it is a bit of fun if you are feeling like you want to revisit an "older" sound while not really sacrificing musicianship.
If you already like Metric, it is an easy buy. If you want to check them out, I'd stick with some of their earlier work to get a feel for how they have changed over the years (i.e. more of a rock feel to a more mainstream throwback).
It is growing on me.
