1. Nirvana -- just to say that I saw them live. I still love the grunge music era. I had friends go to the Omaha show when they toured after Nevermind. Still bummed I didn't go.
2. Van Halen early 80s -- 1984 was one of the first albums I ever had, and I think they were at the peak of their powers then. I am sure their 1984 tour was great as they mixed in new songs from the 1984 album in with the classics from the late 70s.
3. Led Zeppelin -- I am not a huge Zeppelin fan, but it would have been great just to see them rock out for 2-3 hours
4. Smashing Pumpkins -- another one of my favorite bands on the 90s. They didn't have a huge song catalog, but I would think they would put on a decent rock show for a 90-120 minutes.
5. Rush in the late 70s, early 80s -- I saw Rush live in 1998, and it was a great show. It would have been cool to see them when they were young pups, playing their hits from the 70s and 80s.
