Let's see. As mentioned in the thread that nobody replied to, I was at Stavanger Punk Rock Festival, where I among others got to see the Misfits and the Exploited. I've also seen a whole lot of other punk bands during my three other visits to this festival, the most famous possibly being Anti-Nowhere League (the guys who have the song So What, covered by Metallica).
Outside of the punk rock festival, I've seen bands such as Turbonegro, Gothminister, Tristania, Kaizers Orchestra, The (International) Noise Conspiracy, and, well, lots of others. While I've been a member of the crowd of all I've mentioned, I've also worked at several concerts, which ups the number of bands I've been able to watch considerably.
