I wish I had seen them. Doro's solo band afterward had some really strong output as well, but she ultimately started doing WAY too many ballads and not enough rockers for my taste.
Also, you shouldn't trade Appetite for anything. That album, no matter how many times you hear it, is a timeless classic. Also:
1) It's an audio textbook on how to play rock drums.
...
There are some good songs, but that band just fell out of favor with me very quickly. I can assure you, the trade was well worth it.
However, I have to admit, I wasn't really into drums back then, so I've never paid close attention to the drumming. I'll have to take a closer listen from that angle.
I'll also add that if the day ever comes that I actually DO get to see you play and jump up on stage with you, I would TOTALLY be down for doing Paradise City.
