I wanna say Metallica/Iron Maiden a few years back. Oh Bruce and his antics. Wish'd I coulda seen his solo stuff...wicked awesome!
Cheap Trick - loved 'em. Saw 'em with The Romantics way back in the 90's I think. At some amusement park in NW PA of all places
Dang, I think I saw Quiet Riot there too.....lol wtf...musta been hard times
Journey and Def Leppard - Journey rocked.....DL....eh.....left about 2/3 way thru their set. Joe was just trying WAY to hard to sing
On the other hand, saw DL for their 'Hysteria' Tour.....daggum that was a good time
Brian Adams/Eddie Money - Now THAT was a good one. You could close your eyes and think you were listening to Adams on the radio.
dang, I prolly just listed all the concerts I've ever been to lmao. Not too many, but it is what it is I guess
Edit- Elton John up in Canada somewhere (Toronto?) in the late 90's I think. Was pretty good, but we were so far back that the sound from his voice would arrive a couple seconds after you saw him sing the words on the JumboTron or whatever huge display was there lol
