This is the last and easily the best of the Fringe soundtrack albums. The show itself took a somewhat bizarre turn in its final season, having started as a basic procedural with supernatural monsters, slowly but surely adding romance, political maneuverings, and philosophical elements, and then suddenly becoming a dystopian action adventure. However, the score is one of the main things that holds it together. Despite the shorter season, the album is as long as the others (a solid 1.2 hours of music), and maintains the classic Fringe sound of expressive celli and wistful solo piano intermixed with electronics, while brimming with energy. The rarely used top keys of a piano accentuate the heart-wrenching conclusion.
I'm hovering on 4.5 stars; it's still a purchase mostly for fans of the show and its sound but I'll go for 5 stars. If you aren't a fan this album might make you one.
