It's already been in heavy airplay on the local NYC rock radio stations. 15 years have passed since the last G'N'R album was released - this even surpasses Def Leppard for length of time between recordings
I find it just so so and uneventful. Perhaps it it was released a decade ago I'd have found it to be different. SPIN magazine give it a 3 out of 5 stars. You can google the review if you wish.
