This album is a compilation of Unsane's early singles. Like their debut album (which can also be found here) it has been unavailable to buy for several years.
The original CD is comprised of various singles and EPs and has an erratic volume level. In this download, each track has had its volume adjusted individually and then been saved as a high quality 320kbps MP3, giving the album a more consistant volume level. It isn't perfect, but it's a lot better.
