described Raider Klan's Southern hip hop style as "gritty" and "macabre", and Miami New Times described their music as "trad in the battering sounds of SoundCloud rap, a blood-raw strand of hardcore hip-hop largely pioneered in South Florida". The group often used a dark and lo-fi style of production. in 2018, HotNewHipHop said "For over a decade, Raider Klan has been making noise in Carol City with records featuring the same distorted bass, intentionally choppy sounds that we hear throughout Lil Pump and Ski Mask the Slump God's records today". Raider Klan's sound was derived primarily from the early work of Memphis hip hop group Three 6 Mafia, while also incorporating elements of emo, househardcore hip hop, drill and horrorcore. In a 2019 interview, Denzel Curry cited Odd Future as an important influence on the group. Lyrically, they focused on topics ranging from drugs, sex and money to witchcraft, demons and hotep philosophy. Raider Klan were one of the first underground rap collectives to integrate the style of early-Three 6 Mafia into their music, a pattern subsequently embraced throughout the hip hop scene, namely in the form of ASAP Mob and Drake. In 2018 article by Pitchfork writer Alphonse Pierre described Raider Klan members and affiliates such as Denzel Curry, Xavier Wulf and Bones as pioneers of the Soundcloud rap movement. The group's form of lyrical self expression was cited by Genius as influential to emotional rappers like XXXTentacion and Lil Uzi Vert. HotNewHipHop described Night Lovell's style of emo rap as heavily influenced by the music of the group. Ronny J's style of production was heavily inspired Raider Klan, incorporating them into tracks for rappers like XXXTentacion, Lil Pump, Smokepurpp and Ski Mask the Slump God. Rolling Stone described the music of Soundcloud rappers XXXTentacion, Lil Pump, Ski Mask the Slump God, Smokepurpp and WifisFuneral as derived from Raider Klan's material.
Aesthetics
From the beginning of their career, Raider Klan made use of hieroglyphs-inspired text. The origin of the style came about through SpaceGhostPurrp's fascination with Kemetism and Egyptian mythology, and as a way of having a language only members and fans of the group could understand. This style would eventually come to be used by other groups such as ASAP Mob. The group's album covers often include features such as cannabis leaves, skulls and Horror film inspired fonts. Raider Klan members often wore all black clothing, which SpaceGhostPurrp explained as being to represent their "black hearts". Because of this, in a 2012 article by the Guardian, writer Kieran Yates described them as "rap goths".
