Damn this is sick. As far as the instrumental goes, I love that I keep finding myself starting to get into a groove, nodding my head and all, but then it gets all disrupted and suddenly I'm being surprised by what's going on. I love music that keeps me on my toes like that.
And for vocal delivery - the cadence is what really sells this for me. The way the words flow from one to another is great. Really into it. Looking forward to checking out your album you posted here too.
