My boys recently asked me for a list of bands I've seen live. Following are all the (non-classical) concerts I can remember off the top of my head, in roughly chronological order. I've included links for every band or artist, in case you say to yourself, "What the hey?" and want to know more.
The Police (again)
U2 (again)
Felicia and the Hotheads
New Kingston/Collie Buddz
Great Big Sea (again)
