“It's funny we laugh about it now cause that’s the era where he [Eminem] was just sobering up and he was still coming out of those accents. I was so happy and it was so dope at the time but he was kinda like over the accent thing.
“A couple times he’s been like, ‘Yo my bad I had to give you one of the accent joints for your album.’ Like are you kidding, if I can get an adlib from Eminem I'm lucky. He's the greatest, possibly, of all time. Regardless of me DJing for him. Em is the man.
“I worked for him too he's a great boss. Great guy. Good rapper, pretty good. I'm expecting big things from him, if he keeps it up, at least some jewelry for this Marshall guy. The kid’s got something, a little spark.”
