The tall guy with the red shirt is Simon Thauer. He is connected with the Kit Kat Klub in Berlin, Germany, which is probably where this was filmed.
www.kitkatklub.de They have produced a fairly extensive library of videos documenting some of their parties and goings-on during the Love Parade. Check out Lumpi- she's a hottie.
If you didn't know, the Kit Kat Klub is a goth/fetish/sex club.
Of course, when I lived in Germany, I only rented the tapes with the golden stuff.

Based on what I saw that they had available 4 years ago, I can only imagine what their selection's like now.
BTW- I've never posted anything here before because I've never seen anything anywhere else that wasn't already here as well. No sense making reposts, y'know?
