I was told that there wasnt any promotional effort or publicity about it. Most people didnt even know they were on tour. And this is funny, the people that did know, half of them didnt even now Axl had a new band.
Guns N' Roses released four press releases in regards to their 2002 tours (two for Asia/Europe, two for the U.S.), not to mention the various press releases that the venues/festivals released. These press releases garnered significant press coverage of the tour. Guns N' Roses also announced their return prior to the U.S. tour by performing on the MTV Video Music Awards and giving MTV a rare Axl Rose interview. Guns N' Roses revamped their website to bring visitors info regarding the tour. Guns N' Roses did radio interviews in many of the cities they played. Guns N' Roses released a large line of memorabilia (shirts, hats, pants, ect.) promoting the "Chinese Democracy" World Tour. Guns N' Roses had street teams handing out free postcards and shit outside the venues. Guns N' Roses were front-page entertainment news starting with the first date of the tour, thanks to the Vancouver riot.
Other than releasing the album, what more could Guns N' Roses have done to promote the 2002 tour?
The poor sales of that tour are a reflection, in my opinion, of the size of the venues Guns N' Roses chose to play, not of the promotional efforts for the tour.
