Lollapalooza 2015: Thunderstorms cause an evacuation, One Direction makes an appearance, and Florence + the Machine shut it down

Once again, this year's Lollapalooza was a massive success ... spare some spotty storms.

Due to some isolated thunderstorms over the midwest, the Grant Park, Chicago music festival saw some temporary concert postponements and even an evacuation due to high winds. The grounds were forced to close for 90 minutes on Sunday due to the inclement weather. Thankfully, no performer had to cancel their set.

This year's Lollapalooza saw an epic lineup, which included upcoming acts Ryn Weaver, Zella Day, and Halsey along with larger acts Sam Smith, Tove Lo, and The Weeknd. Headliners included Paul McCartney, Metallica, and Florence + The Machine.

Plenty of non-performing celebrities made an appearance at the festival as well, including One Direction ... minus Harry Styles.



Fan favorite Tove Lo enjoyed an incredible set on Saturday. The turn out for her performance was surprisingly fleshed out, even with her set time being earlier in the day. She even returned to stage at night, to join DJ Alesso, for their recent radio hit "Heroes (we could be)." For the performance, Tove Lo dressed up in an angel costume complete with wings.

Here's a post from Tove Lo's Facebook page. The indie pop singer clearly enjoyed playing Lollapalooza.

Florence + The Machine shut down the weekend long music festival on Sunday night. Literally, she was forced to end her set 30 minutes early due to the weather. Of course, that didn't lessen her energy or level of captivation ... or stop the attendees from having the time of their lives.
