Found this video in my recommendations the other day. The title is self explanatory, it's a documentary about the origins of Memphis rap, a really underground genre dating back to the 90s. Back in 2017 when I was high all day everyday, my music of choice was phonk which also has it's roots in Memphis rap, especially in regard to the beats and vocal samples. Definitely worth a watch.
Here's one of the pioneer phonk mixes. I'd recommend listening to it with your best speakers, because the bass adds to the experience.
I'll drag this a bit further: Before I got into phonk I discovered Lo-Fi hip hop, which I'm sure some of you may have already heard of. The mainstream Lo-Fi from today however rarely ever features vocal samples. This is one of the first mixes which I've listened to which got me hooked on the genre.
Another mix, arguably the best of all time, got taken down from YouTube because of copyright issues, but I'll provide the soundcloud link.

This is basically the evolution of my Lo-Fi/phonk taste, the correct order is from bottom to top. This may not float everyone's boat, but I'm happy if I introduced at least one of you to a new facet of the hip hop realm.
