Let the rat race begin.

At 10 a.m. today, three-day passes to Lolla 2015 will go on sale here, for $250 if you're one of the special early birds and $275 for everyone else. Though there's still no lineup, the tickets will likely disappear in minutes. The 300,000-capacity megafest (running July 31–August 2 in Grant Park) has sold out every year since 2011, and did so in record time in both 2013 and 2014. Last year, early-bird three-days got snapped up in 15 minutes, and the entire batch was gone within an hour—some speculate scalpers loaded up on them to flip passes for upwards of $5,000 on StubHub. So: If you want to go to there, update your Front Gate ticketing info in advance and have your credit card number copied to clipboard at 9:59.
