My life in music

As most of you know, seeing live music is a passion of mine. Recently, I started thinking about just how many concerts I've been to and I guesstimate it's about 500, including local bands I've seen around town.
Anyway, I thought it would be fun to try to create a complete list of all the concerts I've seen over the last (yikes!) 20 years. I'm sure it's impossible to get them all, but that's my aim. If you notice any missing or incorrect shows, let me know and I'll add/fix them.
