for me it's Chester Bennington
then, there are lots of other artists I would have liked to have seen, but they weren't even active when I was born.
so, of those I could have seen but didn't because I didn't have the money for the ticket, for the trip, etc., I think it's definitely Linkin Park (so, Chester of course), Chris Cornell and Layne Staley.
maybe I'm forgetting some.
what's yours?
