I'm not an elitist at all, far from it. You really don't have to be to not like something. Particularly not if what is in question is this album
As for your question - thousands. I know it is unfair to compare things. After all GnR were a product of their time and they were very popular at the time, so it's natural that some attention comes Rose's way. Can't really compare it with modern days, because the music industry as it was does not exist anymore and in particular for rock bands there's hardly any market at all. Certainly not a real mainstream market. Other music types don't compare at all really.
But if you want names - I watched Extreme on Monday night at the Astoria in London (they come from a similar timeframe, if a bit later), and that's a completely different level from what GnR ever were and certainly what Rose today is (can hardly call it the same band anymore imo). I'm talking pure musical and songwriting talent here, not the talent to sell yourself. That's something different. Anyway, no media coverage whatsoever, no marketing for their (excellent) new album. I'd consider that unfair.
Then again it was a brilliant, sold out show. So can't really complain too much.
