I couldn't think of a specific song on that album, so I put it on for a listen. I wasn't familiar with the hardcore/punk style on War and Keys to the Kingdom. Funny enough, I had tickets to see them on this tour because Rise Against was their supporting act, but the tour got cancelled because Chester got sick. The pairing didn't make too much sense to me at the time, but now it makes more sense, even if it was at a time that Rise Against was losing a lot of their melodic hardcore background with Appeal to Reason. Collapse (Post-Amerika) still hit though.
