Last night in Boston, MA, EDM icon Kaskade surprised an unsuspecting fan who was re-selling tickets to his show on Craigslist. The fan was scalping one ticket for Kaskade's show at Bijou in Downtown Boston for a whopping price of $200, and Kaskade did not approve. The rest of the story you can get from Kaskade's Twitter feed, and we've got the screenshot below:UPDATE: Kaskade posted a video of the prank to his Instagram today, with the caption, "Friends don't let friends scalp."
