If you want to know how Conor Oberst feels about politics and all sorts of other Big Questions (which let's face it, you all do...), don't look to Bright Eyes or his solo stuff, because that's mostly love and darkness, and don't look to Monsters of Folk, because that's mostly co-written. Look to Desaparecidos - ten years old now, but recently reformed for a one off show, so I understand. Even their name means 'people who have been disappeared', simply - victims of politically motivated imprisonment or murder.
Oberst is quite versatile, it seems: he's done stuff that others have called 'emo', as well as folk, soul, rock. I'd call Desaparecidos rather raucous punk. Have a video.
