I won't bother with naming all Belgian bands I've seen, since you all won't know them

Maybe someone knows Milow though? I've seen him a few times, he's been getting pretty big around the world for the past 2 years.

And the Scandinavian people might know Kurt Nilsen.

I can't really compare much concerts with each other.
I mean, like, Britney Spears, I could only compare the show, which was quite good though. The 1 song she sang live was terrible :/

Bruce Springsteen doesn't need a show, he just needs to stand there and do his thing with his band.

Maybe Lady Gaga and Pink's shows can be compared a bit, because they do make a huge act of it all the time.
I like Pink's voice much better singing live then Lady Gaga, but if I need to look at the act around it, I think Lady Gaga is the winner.
