I'm not a huge concert-goer but I go to one when it's a band I really like, mainly if they come in range of me but occasionally going further afield for special occasions! Random list, not in chronological order because my memory is trash:
* Status Quo
* Turin Brakes
* Shonen Knife
* ZZ Top
* The B-52s
* Vocaloid/Miku Expo
* Man With A Mission
* Mànran
Status Quo and Shonen Knife I've seen a few times; I've even seen Shonen Knife a couple of times with Hornet and Oneeight! Every event listed I've enjoyed, but the freshest in my mind is the Man With A Mission concert which was just back in February, and those guys absolutely slam live.
