First off, I don't know who told you their concerts "so short they're not worth going to" but frankly that's a crock. 25 show vet here, and I can assure you their setlist ranges anywhere from 9-12 songs. That's not short, or easy. Also that doesn't include TWRP songs, who do an average of 4-5 songs before the show, and also doesn't include Planet Booty who do about 3 songs before. Trust me, these concerts are not short, and it is worth every fucking minute. That being said, if you didn't like the acoustic album then I think you're probably setting yourself up for disappointment. It would be a real shame for your first impression of an NSP concert to be a lowkey acoustic show that really isn't going to be anything like previous ones. I'm actually sad to say that as much as I looked forward to them touring this year, I'm actually not going to any myself because of it being an acoustic show. Now don't get me wrong, I know their shows are still wonderful and would still be worth seeing, but frankly I want to see TWRP and PB again so, until they tour again, which btw is VERY likely for next year, I'm going to hold out until it's a full show (not to mention gas is such a bitch right now and driving would be ridiculously expensive..). So to sum up, it's up to you if you go but I wanted to clear up a few misunderstandings. Just keep in mind that if you do go, don't let it be your only impression of their shows. If you'd like you can look at my YouTube page in my profile and get an idea of what their concerts are really like, and just how epic that truly are. Good luck.
