For a long time having Masta on a track was, in my eyes, a sure fire guarantee the track was gonna be a Wu Banger. Ninja style from the mysterious General. All the classic been mentioned on the thread but in particular Assassination Day and Execute Them are as dark as Wu gets and Masta just slices them to bits. Check the solos and search out a dud Masta collaboration. Not easy. First one I can recall not liking was that joint on BDR but I'm sure there were probably earlier ones.

Mad underated dude.
