Saw both Rise Against and Breaking Benjamin live a couple weeks ago. We definitely need to see more of them (Failure is a good grab though) in RB4. In RB2&3 they had some of my favorite songs to play.
Young Guns would be cool too, they were pretty dope with BB, I have seen them twice. Tons of energy on stage. If you guys have never heard of them before, definitely check out the songs I posted.
