Lollapalooza takes over Chicago’s Grant Park this weekend, with a three-day line-up topped off by headliners like Black Sabbath and Jack White, plus highly anticipated sets by the likes of Frank Ocean and Passion Pit. Those come late each day, but there are plenty of reasons to get to the park as soon as gates open. Here are seven of them. These acts all go on before 2 p.m. So don’t oversleep!
