The Flatlinerz are a Horrorcore Rap band from Brooklyn, New York. The band were one of the first bands to coin the popular Horrorcore Rap term. Biography The band were led by Jamal 'Redrum' Simmons (nephew to Russel Simmons) and two other rappers called Gravedigger and Tempest. The idea thought up by Def Jam and The Flatlinerzs was that the band create a style of Rap music that moved away from the popular gangsta rap at the time, and deal with more darker subjects such as Satanism, horror movies and gruesome murder. The band was heavily predicted as the next big thing by Def Jam after they where signed to Def Jam by Jam Master Jay (contrary to belief, Russel Simmons apparently didn't sign The Flatlinerz as he couldn't take the concept seriously) and released their only album, U.S.A (which stood for Under Satan's Authority). The album didn't sell well, and there was a lot of controversy surrounding the videos for Live Evil and Satanic V
