Hollywood Undead took a page out of Slipknot's horror handbook, donning a selection of fright masks as they unleashed their fusion of hip-hop and metal on the world in 2005. Their updated take on nu-metal aided them in becoming the first act signed to MySpace Records, but they never released any music on the label, due to a censorship dispute. Famed for their intense, fast-paced vocal interplay and party-hard attitude, the band went darker and heavier, perfecting their sound on 2011's American Tragedy.
