Lynch is one of the most diverse artists as far as his delivery. lyrical content aside, 24 Deep, SOTS, and Loaded all had different delivery with each album focusing on one delivery style. his rhyme schemes and his vocal rythms were all different with each album. and he got numerous dope ass vocal tones. and his voice is very inviting. and the mothafucka can win American Idol if he tried out or The Voice cus he hella old. and each album made new fans. including his pre 24 Deep shit which also had different delivery. history shows his relative success with each of those albums. he a very creative dude. if dude wasnt a horrorcore rapper he could be makin more money right now. and the mothafucka can get the fuck down with production fuckin with samples or straight electro.
the lyrical content seems to be the only thing holdin him from using his gift to bubble the fuck up. but he's doin what he loves so i respect that.
aint no other rap artists really fuckin with that to that degree. and the only other artist i know of who's as diverse in delivery (but a little more) is Karen O from the Yeah Yeah Yeahs. im a big ass Karen O fan, but i aint really a Lynch fan. im really a fan of his older work (SOTS one of the greatest albums ever, imo), and a fan of what i know he has to offer to the masses.
but to answer your question. yes, Lynch can do what the fuck he wants.
