Query: Politcal Punk at its best brought to you by Anti-Flag

What can I say Anti-Flag out did themselves with "Underground Network" Every song has great message and great vocals by Chris and Justin to back it up. Justin's vocals haven't been better. I feel that the vocals are more stronger than the last three albums. I also like the fact that Chris sang in two of the songs that gave it a unique switch from Justin to Chris. Plus Chris has a cool sound to his voice.I also like the essay's writen in about some of the songs by the authors,thats really cool that they did that. Best Tracks are 1-10,but 11-13 are good but a little slow in my opinion. all in all a great Political Punk CD with a great message keep it up Anti-Flag
