8. Roger Waters
When Pink Floyd brought The Wall on the road in 1980/81, they only hit four cities across the world. It's since become one of the most legendary tours in rock history, so when Roger Waters announced that he was reviving it in 2010 there was incredible pent-up fan demand. It's since been all over the world, but he's spending the first seven months of 2012 taking it to South America and all across the U.S. – even hitting a number of baseball stadiums. When all is said and done he will have 190 concerts under his belt, but he's even thinking about bringing it back to Europe in 2013. A Pink Floyd reunion feels pretty unlikely at the moment, so this is as close to the Floyd experience as fans are probably ever going to get.
