I recall a bit of shock when I put on Lyricist's Lounge and heard Zack doing a collaboration with KRS-One, and it was quite good. Based on that, I started to seek out all his other guest vocal performances and came up with this list, I think it has most of them. I didn't include One Day As A Lion as that was on a recent mix, and Farside where he plays guitar because I just didn't like it and it didn't fit in anywhere on this mix. He also played guitar in Hard Stance, so included that as it fit the vibe towards the end of this mix.
