Also, are you able to elaborate on Memphis rap sigils? Pretty sure I saw a thread on this the other day, which I skimmed through, but I didn't gain any insight into what it means

Sorry was afk. I don't know much about Memphis Rap Sigils aside from stuff I've picked up on /x/ and general knowledge about some of the artists involved. 

Basically, there's speculation that many of the 'underground' Memphis Rap artists that eventually saw success were involved in Satanic/Goetia practices while making their music. Many of the original mixtapes that were put out have hidden sigils on the Album art, and some of the sounds sampled on these tapes is thought to be recordings of victims being sacrificed for the groups future success. 

These are super hard to find, and alot of them have been lost, but Memphis Rap in general is almost entirely responsible for the rise of occult themes in modern day hip-hop. Check some of these guys out regardless, it's really raw :)
