It's slick as fuck!
I don't know, but i get the impression they completely reworked Hard Skool? And I think it sucked, it sounded like Hollywood Rose, where it should have sounded like Better part 2. Axl is great on that track and everything else, except for the solo, is wank compared to the demo.
This sounds like a nugnr track with Slash and duff tastefully adding their input, not completely reworking the songs from the drums up (which they might have done, but it doesn't sound like that, if so, great work!).
It's how the CD stuff should be treated and they have done an amazing job on these tracks.
