All the promotion in the world wouldn't change anything.  This is not AC/DC - not even close - even if you ignore the different eras.  Anything short of Axl and Slash will not equal GnR to the public, therefore will not be accepted, nor will it sell.  CD = Contraband...some sales due to the curiosity factor.  If there is a next album, consider it Libertad (which I like, but it was clearly a failure).  They could promote the shit out of whatever band they have together at the moment and it wouldn't matter.  Half of them weren't featured on the existing album and if there's ever another album, half of them won't be on that album either.  And nobody is waiting 15 years for another Axl Rose record, so anyone that thinks they can rebuild the hype is mistaken.

The album that just came out only really has Axl, Tommy, Dizzy and Pitman making significant contributions with other additions forced in here and there for some reason that is completely beyond comprehension.  Until otherwise proven, there's no Brain, huge, BH, or Finck in GnR anymore.  There are as many contributors still in the band as there are out of it.  There's no way you can compare this to AC/DC, which really became famous after Bon died.  The best AC/DC / GnR comparison would be the Ole Bach era to the AFD era.

AC/DC is completely different.  AC/DC lost one guy in a band that was known, but not huge 5 years before video even made who was in a band common knowledge.  Fast forward to the video era where GnR was for a short period of time the biggest in the world now replacing every single person other than the singer from their landmark album that used videos to identify who they were.  It's not even apples and oranges.  Journey, Styx, Motley Crue, Poison...the list goes on and on for 80s bands that were never given a chance without the lineup that made the band famous.  Had Bon died post AC/DC really making it, they would have had the same fate with Brian Johnson.

Video changed all the rules - names suddenly had faces beyond the lead singer.  Once that happened, it changed the entire complexion of the music industry in so many ways.

I don't believe Bush made up stories about terrorists.  Exaggerated?  Maybe, but there was and still is a clear terrorist threat in Iraq.  If not, Obama wouldn't have backed off his timeline for leaving Iraq.

Bush = terrorists
Obama = pirates

The more things change, the more they stay the same.

Correct - gotta go dodge a tornado.
