Underground rap track

Hi folks,

This is my first request, and hopefully someone knows what it is because it's a sick tune.

Here's what I know about it: it's part of a DJ King Flow mixtape (2009?), which plays occasionally on ChamberMusik.com's radio station on Live365. The mixtape begins with Scarface presents The Product - G Type.

Managed to find it in the end: it's K Sparks - Black Rose.
