Libertad is a good solid hard rock album, but doesn't better their debut Contraband. The albums begins really well, with She Builds Quick Machines being a particular highlight, and is resonably solid through till the end, bar a few poor songs.
In order to truly enjoy this album it takes a few listens from beginning to end. At first listen I was asking myself what were they trying to accomplish, but by the fourth or fifth listen I enjoy every track on this album. It may not be for everyone, but it is a solid rock album that you can throw in the player for a road trip or a day at the beach.
