Ski Mask the Slump God, from Broward County, Florida, is known for rapid-fire, playful flows and a cartoonish edge, and he co-founded Members Only with XXXTentacion. These beats leave room for that kind of fast, animated delivery.
Nearly all of them are trap, nearly all feel dark or bouncy, and a few lean experimental. Some also carry JPEGMAFIA, Denzel Curry or JID tags.
Start with "Fashion Show", the most-viewed beat in this set on YouTube.
