the Gza/genius is an institution of great lyrical content. unfortunately thats all he's got.
his rap presentation is horrible. the guys flow is almost non-existent and his delivery sounds like he's rhyming from bed. you have to be willing to look past these two factors to appreciate this guy.
someone can write the best book report ever but if he gets in front of people and doesnt know how to deliver it, no one is gonna be interested. they wont care how good the content is.
im not saying the guy needs to have delivery like Rza on 6 feet deep and flow like method man, he just needs to step his flow and delivery game up to a satisfactory level. some examples of him with good flow and delivery:
wu banga 101
Gza has always had a laid back delivery but now he sounds like he's on downers. the flow is where he really suffers though.
be nice(nevermind, this is bring the ruckus)
