Lagwagon is a great band as well.

Pearl Jam, has let me down with the last few efforts. Leave political music to people who do it well, I feel PJ doesnt do it well, at all. RATM corners that market in my opinion. Lil to much influence of Neil Young for me in the PJ catalog. Although the Dylan cover of Masters of War is by far the best I have EVER heard.

Rise Against is very political. If you are into that scence as well.
