HELLMOTHERFUCKINGYES!!!!!!!!!!!!!!! As some know, they have been at the top of my to-see list for years and have been really impatient not being able to see them, so I am stoked about this...however, I do wish it was another week as there's a shit-ton of shows early October. This will be number one on my list though.
As for the Arcadia, it's a really odd venue. I went there for Accept last year. It's basically what used to be an old fashioned movie theater turned into a concert venue, with the occasional old film/film festival. Make sure to keep checking the website for onsales though. You won't be able to get tickets on Ticketmaster. The cool thing though is when you do order them on their website, you basically get to pick where you want to be. Just a warning though, those seats are VERY uncomfortable.
