I'll tell you which one was terrible - madonna in 2001. I wanted my money back.
As for best, I've enjoyed a lot of shows for many different reasons. Bon Jovi is always fun. Loved Huey Lewis out at Wolf Trap. I've seen NKOTB multiple times in the past 10 years-fun in a different way. I went with my parents a couple weeks ago to see Cyndi Lauper and Rod Stewart at Jiffy Lube- they still got it

. And I actually enjoyed Shawn Mendes with my 10 year old.
