Either Roger Waters' The Wall show in the Gelredome in 2011, or Rage Against the Machine on the Pinkpop festival in 2008. Both were magical experiences that I would gladly experience all over
I'm 34, so I wasn't around when The Wall was released but I grew up going through my dad's record collection all the time. I've had a CD player since I was 12, and a record player since shortly after, and Pink Floyd has always amazed me. I unfortunately never got to see Floyd live, so this was the next best thing. Still doubting if I should buy tickets to the new tour as well.
And Rage Against the Machine was magical in its own way too. Such brutal, raw energy! It was as if they'd never split, I've never experienced a gig so intense before or after. And I've never come home from any other gig with such a stiff and sore neck and throat
One of the original Wall shows by Pink Floyd themselves would be even better!
