Set between Lake Michigan and the Chicago skyline, Lollapalooza is the city's largest music festival, boasting numbers of attendance well in the six digits on a regular day. Large stages, big acts and huge crowds. Taking over all of Grant Park, Lollapalooza is one of the best festivals in the country with a sweet bonus—no camping. This year, Paul McCartney, Metallica, Florence and the Machine, Sam Smith and Bassnectar top the bill. Beyond the headliners, the lineup is bit weak, but that didn't stop the fest from selling out in minutes.
