This is Jon Schaffer's new side/solo project, and I must say a damn good one at that. If you can look past the heavy political slant of the lyrics you'll find an awesome Heavy/Power Metal album that somewhat reminiscent of Iced Earth's "Dark Saga". Jon does all the vocals himself, and what a surprisingly solid vocalist he is!
The album can be downloaded for free at the SOL website: www.sons-of-liberty.net
The only snag is that you have to subscribe to the SOL newsletter in order to receive the download link, but it's worth it.
