To head off any conclusion you might be (understandably) jumping to, let me clarify: Ace Rock is not a plagiarist. Ace Rock is one of the greatest artists working in Hip Hop today, and (hopefully) he'll only get better. It's just an EP, so it's not quite up to par with one of his full-lengths (which you shoud definitely pick up).
Anyway, unless the esteemed reviewer who refers to himself as "Pike" works for pitchforkmedia.com, he's plagiarizing pitchfork reviewer Nitsuh Abebe's review on Aesop's "Labor Days" album. You can probably spot it where a bad review suddenly turns into a good review. Here's the stolen material:
"That last line's from "Save Yourself," which collects Ace's comments on the How We Do Hip-Hop question-- he's undie, of course, here with his sonically progressive Def Jux release, so clearly he's going to drop some invective on this Important Issue. His take, though? Forget it: "Maybe you ought to try saving something other than hip-hop," insightful advice no matter what genre you insert at the end. "Pistons pump perfect," he says, then, "what you're holding ain't really broken." And for the duration of Labor Days, it's pretty clear that in the hands of someone with something to use it for, it's not, not at all."
If you can't write your own review, then don't.
