Well, that sucks. Apparently Accept has something better to do, so they aren't playing the Atlanta date (although they are playing New Orleans the night before and Charlotte the day after...). Basically I'd just be going to see Kreator play some new stuff, because I've heard all those other tunes time and time again.
Thanks for the post.
