Here's a list of the bands I've seen live. (N) indicates I've been to see a band N times. Also, I tend not to list local shows here (or e.g. any one of the dozens of bands that play at larger festivals I've attended such as Ozzfest). In general, these are the bands who are on the "bucket list", so to speak.
