Sub-genre of
Hip Hop's trap music originating in Chicago's impoverished south and west sides. Where as traditional trap lyrics from Atlanta more so concern drug dealing or 'trapping',
drill music's lyrics are more violent and aggressive, reflecting the violent nature of some of Chicago neighborhoods that made it the murder capital of America in 2012. Drill music was nationally popularized in early 2012 by likes of Chief Keef,
King Louie and Lil Durk among others.
