Hell nah...not in the slightest
You think 3-6 actually heard that "bone enterprise" album when people in their own hometown didn't even know it existed?
They were already doing "dark/demonic" music before Bone had released anything period.
^^^This is from '92 a year before Bone Enterprise.
And just for added measure here's a song from '92 of Infamous using the "double time flow" again, a year before Bone had dropped anything
The demonic shyt in 3-6's sound is partly due to the influence Ganksta Nip/SPC & Geto Boys
Also Bone wasn't the 1st rappers to "harmonize" in their raps...Klondike Kat, from the same group (SPC) that was one of 3-6's primary influences, had melodic flows a few years before Bone.
^^^This sounds awfully similar to Bizzy...a full year before Bizzy even existed
