2. Swim City Black Tie

On Monday, 2 July at 14:00 we are hosting a black tie party at the Roskilde Festival Swim City! Participants are to wear fancy clothes (tuxedos, suits, ties, dresses, whatever you have) and take go for a swim in the lake, hangout, sunbathe, or just relax and cure your headache with classical music. We will act is if it’s a perfectly normal thing to do, and otherwise act fancy while a classical orchestra plays nearby. Just show up at the lake at 14:00 and start swimming in your fancy clothes. RSVP on Facebook here.

On Friday, 6 July at exactly 15:00 we are staging a mass Freeze Mob in the Social Zone. At exactly 15:00:00 all participants are to freeze in place wherever they are in the Social Zone, and stay frozen for three minutes. At 15:03 everyone will unfreeze and act as though nothing unusual happened at all. If you feel like participating then put it in your calendar right now with the alarm set!. You can RSVP on Facebook here.
