It's the rapper from Shadowrunners Click, which the producer from the same duo produced the track so I guess it's pretty much a Shadowrunners Click song.
You should grab Himself's mixtapes though, they are both dope.
That Riff Raff/other dude/A-Wax song is pretty bad on all accounts. I can't stand TrapZillas stuff. A-Wax still somehow remains beyond boring. It's almost getting to the point that it's kind of impressive in it's own way.
Actually I liked that 65 G'z in a Jordan Briefcase album too. Totally lost me after that though. If him Jacka weren't funking they could put out a duo album for coma patients.
