at the moment I remember only 3 of them so this were the greatest I`ve seen :)
I can't say in which order but:
-NIN / Miami / 2000
-Rammstein / Oakland / 2011
-Funker Vogt / Orlando / 2002
-kmfdm / Orlando/ 2006
-Orgy / Fort Lauderdale / 1999
I've had other more interesting music experiences like Burning Man but these were probably the most memorable concerts, usually due to being really young or seeing them for the first time.
