Knxweldge Live in the Dungeon

I post this for two reasons:

1. Knx is that dude and Hud Dreams drops today.

2. I desperately need to know where that Mobb Deep vocal sample is from.  I've been trying to track that down since the Fantastik 4our show used it on one of their intros, but have no idea where it's from.  Any help would be greatly appreciated.
