Disagree somewhat. Mannie had some dark or menacing beats too, whether on all the BG albums (Slim over that production would have fit perfectly), UNLV, 400 Degreez, and the pre-98 non-bounce stuff on CMRDon't think P would have put them as solo artists, I could see them being in a group together.
Beats By The Pound beats wouldn't have registered well with Turk in my opinion. I still today haven't heard them rap over a BBTP beat (I am not 100% sure about this)
Mannie production brought out the worse artist because of the bass guitar and Mannie strings, most of Turk's best verses came off production with 'strings' and bass guitars riffs.
BBTP wasn't really heavy on the same sounds that Mannie used which was (to me) made BBTP production a much more darker, heavy (in a sense) production which catered more on your gangsta rappers.
Slim was a better fit for KL than Mannie, Slim was a gangsta rapper who wasn't about "polish" I think of Mannie production more so "polish" than BBTB production. More of a scrappy, edgy sounds, dark at times.
But nah I don't think it would have worked for them on NL
But Slim or Mac didn't have nonstop dark shyt anyway, so Mannie production would have fit well with em anyway
