Desaparecidos was a short-lived American punk rock band. It was a side project headed by singer/guitarist Conor Oberst, the frontman of the indie folk band Bright Eyes. They have also been hailed as the "Saddle Creek supergroup".[citation needed] Hailing from Omaha, Nebraska, Desaparecidos' lyrics are mostly about the sociopolitical state of affairs in America. The band has been both lauded and criticized for its intentionally raw sound following the release of Read Music/Speak Spanish. In sharp contrast to Bright Eyes' confessional, even sometimes mournful vocals, Conor Oberst's vocals in Desaparecidos' songs were much more characteristic of the post hardcore during the Revolution Summer. "Desaparecidos" means literally "the ones who disappeared" in Spanish and Portuguese, and is a reference to people who were arrested by various South American military governments and then vanished without a trace. From 1976 to 1983 in Argentina, for example, thousands of dissidents vanished without a trace under Dirty War driven by the military junta that was in power.
