A 3 hour GN'R setlist is actually very common in this stage of their career. There's a few factors here: there are multiple Guns N' Roses songs that are 6+ minutes long, some of which are setlist staples (November Rain, Estranged, etc), they do a fair bit of covers, and they usually have at least one instrumental solo. https://www.setlist.fm/setlist/guns...-gnp-seguros-mexico-city-mexico-6b44828e.html
Story of the Year playing the same time as Godsmack just reminded me of the time those two bands got into a fight backstage at a festival in 2003. LOL
and literally for the dumbest of reasons, story of the year played shortly before Godsmack and story of the year was going a little crazy. (What they were known for at the time) and stood/jumped off some of Godsmack’s backline. Fun fact at another radio show a few weeks later Finch and Disturbed got into a brawl too.
Y'know, I knew that happened too! But I always have to check to be sure I'm getting who fought with who correct. LOL! And I didn't know it was within like, a week or two of each other. Wild times. Less fun fact: I once saw Sully Erna at a sports bar in Boston at like, 11am on a Sunday with an entourage that included two women he was obsessed with trying to get to makeout with each other. It didn't work and they left like, 15 minutes later. He's such a pathetic dirtbag piece of scum. Him and that zionist from Disturbed can just fuck all the way off.
That story is a pretty wild read: https://www.ultimate-guitar.com/news/general_music_news/story_of_the_year_vs_godsmack.html
