I've been fortunate enough to see most of my favorite musical acts in person
(and some that I haven't been so thrilled with). Here's as many as I can remember.
As you can see, I have a very wide range of taste in music...

The numbers indicate the number of times I've seen them, as far as I know.
Artists are in alphabetical order by first name.

Footnotes*
I saw the Beach Boys twice while Carl Wilson was still alive. I don't
consider the band touring with Mike Love today to be the Beach Boys in
any way, shape or form.

**I've also seen Vince Neil solo once
