So unfortunately Ganstagrass is the one rap/bluegrass/countey fusion band I've found, but they fuck so hard but I haven't looked super hard yet, meant to take some time to do that today actually so I'll update the post when I do.
But since you asked for recs I have to get my usual recs out since I want everyone to listen to this stuff, so BRELAND, Tanner Adell, Blanco Brown, Reyna Roberts, and Willie Jones are all black country artists that blend a lot of rap and hiphop influence into their music which creates a really great vibe(especially since the white country artists doing this are just not anywhere near as good at it someone please stop Morgan Wallen every single one of his songs sounds exactly the same ahhhhh).
I have to plug Brittney Spencer, Shaboozey, and Tiera Kennedy too but those two do much more pure country, country/rock, and country/pop, and ofc I'd be remiss not to mention Beyoncé's Cowboy Carter album which is just a celebration of country and adjacent generes and black music and fusion stuff it's crazy just listen to the whole thing.
I also reccomend the Pony Up remix of Texas Hold 'Em but I hit the link limit.
As always, if anyone else has any recs, feel free to drop 'em here, I am ALWAYS looking for more country to listen to and I would love to have some more country/rap stuff like genuinely so bad pls.
