Okay let me just say if youre ever in Berlin and people tell you to stay inside on May Day or you'll get pelted with rocks DON'T LISTEN. There were little children in strollers, elderly and many in weelchairs all having a great time so WTF are these pussies talking about? This may be the best event I've ever attended and I got great video doc. We ate falafells and drank beer in the streets of Kreuzberg all afternoon into the night and there were various stages around. We saw a middle eastern band (sounded Egyptian but not sure) and a belly dancer, then a Persian band, then we watched a very impressive break dance battle, then a not so impressive flamenco dancer, then we saw a Turkish band and danced with the locals who totally welcomed our white asses, then some really terrible punk rock bands. Oh and I got some really interesting footage of demonstrations (May 1st has interesting political history, if you don't know it looki it up) So yeah it started to feel/ get rowdy towards the end but it was fun not scary 
temper:
Oh, I swear to god, it used to be NOTHING like what it is today. Actually just last year was a huge turning point where things got dramatically less violent, and the whole thing switched from being a riot to a carneval, or something. But berliners ceased taking it seriously quite a few years before that, since it turned from a deeply political, despererate labor-day demonstration to a tourist attraction farce where no one knew the history or what the whole thing was about anyway... Too. Bad.
alsana:
Yeah even at UDK when some girl asked about May Day history they told her it was just a bunch of angry anarchists and they didn't know anything else. I wanted to speak up but it wasn't the time or the place.
