@EmIsGodOfRap yea alot of people don't know this but slim actually broke out in 1997.. he was a huge underground rapper then and was getting booked all over. then he got signed by dre then the rest is history.
I bet even though these people didn't know exactly HOW BIG Eminem was going to be, it must've been undeniable to say to oneself...damn...this guy is gonna do big things...He's far above the average
