Def Con Dos or DCD (Spanish for Def Con Two) is a metal rap band from Madrid, Spain. Greatly influenced by hip hop bands Beastie Boys, Public Enemy, and Run D.M.C., and rock band Siniestro Total, they started rapping over hip hop bases created by producer Julián Hernández (musician and singer of Siniestro Total). In their Segundo Asalto tape (1989), the sound still was basically hip hop, but they started using rock guitars. Since Armas pal pueblo, the sound has been evolving into rap metal, with touches of techno and nu metal.
