I actually forgot to mention AC/DC - may have actually been second (or first) album I ever bought - For Those About To Rock - just awesome and I finally saw them in 1990 on the Razor's Edge Tour. A non stop show, amazing, it is my top 10!
Funny, thinking back on it (i actually have most of my ticket stubs to this day, looking over them), I am not sure I ever saw a "bad" concert.
Most economical concert I saw was the $5 per ticket General Admission Lynyrd Skynyrd Marlboro Military tour on military bases. I still crack up when they unveiled the Confederate Battle Flag during Freebird right on the base! No one said a word in 1995, but my goodness if they did it today, they would be banned! They retired last year and in order to avoid the hypocritical media, they started wearing Earphones with Confederate Flags on them and using the American Flag as a backdrop. Funny, Hank Williams Jr. still uses it today, as he says, the publicity is great and he continues to sell them out at ever show (in every State) (he sells one with his face in the middle of it).
