Edward Sharpe and the Magnetic Zeros. As lame as it may be to see an American band in a foreign country, there was nothing remotely lame about this concert. It was awesome.
I was realizing that it had been a while since I had seen a real band, I was just used to seeing DJs (no offense to a certain someone) who, while they do perform music, are not necessarily creating their music on the spot. When you watch a live concert there is something special that the audience contributes, and I could feel that in this venue.
First of all, the lead singer, Alex Ebert's constant supply of weirdness and energy kept the crowd going, at one point he said, "I think I'd like to get a little closer" and calmly walked off stage into the crowd next to us and sat down. The entire venue sat down with him as he sang the song "Brother" campfire style. You could tell the base player on stage was shaking his head going, "Damn, Alex does it again."
