The Flyer says it all. And if you can't guess who the "secret guest" might be, check out this dose (you should be able to figure it out):
Justice - Waters of Nazereth (Erol Alkan's Durrr Durrr Durrrrrr Re-Edit) (with Pase Rock guest drop)
If you haven't guessed by now, all the featured track come from this humdinger of an album. If you haven't yet got it, I suggest you go here and cop it now; better late than never.
