Two of my dream collaborations are featured on Killer, Scarface and more importantly Ice Cube..
I would hope collaborations with DMX, Busta Rhymes & Eminem are fulfilled before Tech N9ne's career comes to a close.. I think they are all pretty attainable considering Tech knows DMX & Busta Rhymes personally.. Busta Rhymes on a track where he does the hook would sound amazing..
Other than that, whose better a collaboration than people already on the Strange Music roster.. Calhoun, Kaliko, Skatter/Snug to a lesser degree..
