Here's a little YouTube video, at around two minutes especially, you can see the crowd I was in trying to take these pictures. I think that explains it all. The video is worth it to watch Ninja dance. He's awesome. Also, for the gentlemen (and select ladies) out there, Yo-Landi is wearing a cut off shirt and you can see underboob. You can't really see them until around one minute in.
But seriously guys, I tell you, even if you think their music is weird or silly you should REALLY see them live. They are such great performers.
