Three 6 Mafia, originally known as Backyard Posse and Triple 6 Mafia, is an incredibly influential hardcore rap group from Memphis, Tennessee. Started in 1991 by Juicy J, D.J. Paul, and Lord Infamous—who died in 2013—Crunchy Black, Gangsta Boo, and Koopsta Knicca have all been part of the Mafia.

Mystic Stylez, their 1995 debut album, inspired a lo-fi Horrorcore movement in the 2010’s; SpaceGhostPurrp, Denzel Curry, $UICIDEBOY$, A$AP Rocky and Lil Ugly Mane all were influenced by Mystic Stylez dark sound.

The Mafia is also known for coining the term “crunk,” a style of music famous for heavy basslines and shouted vocals.

“It’s Hard Out Here For a Pimp,” off the soundtrack to Hustle & Flow, won best original song at the Academy Awards in 2005.

The Three 6 Mafia is responsible for kick starting the careers of Frayser Boy, Gangsta Blac, Lil Wyte, Indo G, T. Rock, Playa Fly, Killa Klan Kaze, La Chat, and Al Kapone. The group frequently collaborates with Project Pat.
