Wun Two, Tuamie, Knxwledge, smuv, Made in M, ShunGu, and especially Fitzroy, in my opinion just to name a few off the top of my head. All found on Soundcloud, all dope as fuck, you'd love em.
Fun Fact: The original beat was created by Easy Mo Bee who was the one and only producer to have ever worked with both Biggie and Tupac. I know some of y'all love this version of it more, but don't disrespect the original instrumental. Easy Mo Bee's version goes hard a'f to me as well because it has that Old School feel to it that I also love. None of this would have ever happened without the classics!
