I did end up going to the Apoptygma Berzerk / Dismantled show last night. I actually thought Dismantled put on a pretty good show themselves. I liked their live music much better than recorded.
Apop wasn't bad at all. I enjoyed the show. I didn't think the live instruments overpowered the music, and most of the songs were recognizable throughout. They actually had a keyboardist, which I was under the impression they'd be without, and usually there was a strong electronic influence in what they were playing. But there were times when it seemed more like an alternative rock concert than synthpop.
I'd pay money to see them again, but I totally understand the criticism Creepster and Berger Stahl had for their live show. It was different from their albums for sure.
glad you enjoyed it and didn't give into peer pressure
