According to early news on the Accept-forum, Kreator is the headliner. People on that forum have some contact with the Accept management so there should be some truth to this. But both bands probably have the same playing time (around 70 min).
I have got to start listening to more Accept. Because of you, I do know the band a lot better now, but there is tons that I still have to hear. If you get the time, I’d totally dig it if you would suggest albums, or even single songs for me to listen to that will make the show more enjoyable for me. I want to sing along and be festive like everyone else, ya know?
