oh shiiit, now i know who they are, i seen an interview with blu and exile a couple of weeks ago on a deutsch hiphop website lol but i couldnt remember their names, that exile dude was freestyling a beat on the mpc which was pretty fukkin dope actually
I like Blu a lot and this verse fits well stylistically.
Why would he appear on a song dissing 50 though? Seems a little random.
Also having him on the record implies, from a battle rappers point of view, that GZA couldn't handle 50 by himself.
His verse isn't quite lethal enough to follow up GZA's therefore, diluting the original record. I bet they threw the joint out there to see who would be interested in jumping on it and Blu did a demo for it and may or may not have turned it.
