Game Theory popped into my head first because I don't even think Roots fans fully appreciate that classic enough. The two albums since pale in comparison...

Masta Ace is a good call too....and now I'm going to have to dig out Blast Radius and I'm about to check out Poor People's Day.

I gotta give a nod to The New Danger though. BOBS remains his best, Ecstatic is his most consistent...

But if you took 3 or 4 songs off The New Danger?? Damn.

A few heaters-
