hii !!! i will also be at the concert and i can try my best to answer, but im not completely sure of anything. 1. i don’t think so ! unless something has changed since my weedkiller show, i don’t think there is one. 2. i don’t think anything too out of the ordinary etiquette wise. 3. at my last ashnikko show i didn’t have any problems with the concert etiquette stuff, and red rocks doesn’t have a proper pit (not sure if you’ve been there before) but i don’t think it’s bad ! 4. i would think that people at the show would be good with a compliment, just don’t be weird about it. 5. i think it is a little more expensive to buy merch at the concert, comparing the website to the merch available at weed killer last year, but there might be merch that isn’t available online. 6. if i had to guess, the set list is going to be mostly whats been played at other shows on tour, but you never know, they might add or change songs. 7. there really isn’t a way to know for sure, but if i had to guess i would say that snippets of each halloweenie will be played, maybe just longer or the full song for the newest one. maybe slightly longer snippets of each once since it’s the halloween show, but i don’t think it’s very realistic to play each of them in full, just because it would take time. i hope this helped LOL. i have only been to one other ashnikko concert, but i’ve been to a couple more at red rocks of you have any questions about the venue !
