Flogging Molly at the now closed Beaumont Club in KC was phenomenol! Prefaced with Irish carbombs and a great group of friends. Just about perfect. Most of my favorites were all smaller venues: BB King, Jimmy Buffet, Blue October, Sevendust, Offspring. Best stadium show was when little known Godsmack opened for Metallica in Rockford, IL. Oh, and Dropkick Murphys absolutely bring it every time I've seen them.
My first concert was also cool. Saw Kiss when I was 10. The doors opened the surge of people pressed together so tightly that I was lifted off my feet and I didn't hit the floor till I got up in the pit area. Great start to my concert going
