Shows by state, with a dot at every venue
The timeline shows cumulative performances I've attended. The hollow dots mark festivals, which are generally responsible for the large bumps. Festivals are nice (depending on weather), but I've sworn off going to them after Vans Warped Tour coincided with Ozzfest 1998, a wonderful show, but just too many bands across too many stages without a good schedule.
I enjoy a good show and have attended quite a fair number in my youth. I've got the tinnitus to prove it. I didn't do much in terms of keeping track of which concerts I attended and when (I used to have all the ticket stubs, but lost those), let alone who the opening acts were, but I've reconstructed everything before 2010 as best I could. The 90's remain a bit of a blur.
