Concerts that have marked you somehow

[(Hidden)]

Which concerts have marked you somehow in your life (for whatever reason)?

For me, one of the concerts that has marked me very much was Madonna's Sticky & Sweet Tour in Madrid in July 2009 because it was one of my first concerts ever in my life (I had to go with my parents because I was under legal age to attend a concert) and I remember every single song from that concert!

Kylie Minogue and her Les Follies Tour.

I was in the first raw, waiting since 7AM lol and everything was incredible: songs, remixed versions, clothes, staging, water jets... One of my best moments!
