There are two major ways Three 6 Mafia have impacted today's sound. The first is in production. As was made evident on Juicy J's latest album, produced by Mike Will, Young Chop, and Lex Luger, the production style pioneered by Three 6 Mafia and other Memphis acts in the mid-1990s is still reverberating today.
Of course, Three 6 are just one strand of influence in club rap's current production style. (DJ Toomp, for example, also deserves a significant portion of the credit.) But Three 6 impacted the art of rapping as well. The group was a part of an underground tape scene in Memphis in the mid-90s that innovated certain flows and rap styles still used today. Alongside Ohio's Bone Thugs N Harmony, Three 6-affiliated artists like Kingpin Skinny Pimp invented an approach to rapping that proved widely influential on artists throughout hip-hop, both within Memphis and nationally, including groups like A$AP Mob and Raider Klan.
