Been working on collecting revolutionary, or at least anti government music. So far I have stuff from:
Immortal Technique (https://www.youtube.com/watch?v=9J7yK1TPkDo)
Sage Francis (https://www.youtube.com/watch?v=poZz2bKaonM))
Rise Against (https://www.youtube.com/watch?v=_RYBDTnS7dg)
Jedi Mind Trick (https://www.youtube.com/watch?v=3qpcyJ-nse0)
Scroobius Pip (https://www.youtube.com/watch?v=ljcqNORe3F0)
Aesop Rock (https://www.youtube.com/watch?v=3tZtish6RPU)
Bad Religion (https://www.youtube.com/watch?v=12kcpP-8jfM)
Rage Against the Machine (https://www.youtube.com/watch?v=dxk3c_SbWMg)
Note: I'm not saying I agree with all these guys politics but their music gets me nice an enraged every time I start to get complacent. Add your favorites
