National acts I've seen, in mostly chronological order:

Joe Cocker, Arthur Feidler(Boston Pops), Nada Surf, The Bodeans, Jewel, Guster(97'&99'), Tonic, Verve Pipe, Face to Face, Weezer, No Doubt, The Saints, Jesus Lizard, Bush, Rebekah, Matchbox20, Eve6, Third Eye Blind, The Dickies, Lit, Offspring, Angry Salad, Shootz Groove, Jimie's Chicken Shack, Splender, Live, C60, 6Gig, Disturbed, Fuel,...

I'll admit that I don't remember Joe Cocker, and that the Pops one is a bit fuzzy (I was 3 or 4).. I didn't go to a concert on my own until I was 19 or else there'd be more shows I'd gone to. If you're reading this, I'm worried about you.
