What: 2013 Lollapalooza festival

When: August 2-4, 2013

Where: Chicago's Grant Park

Why: The return of Nine Inch Nails as one of the festival's headliners will definitely be a top draw. Though Lollapalooza offers an eclectic bill, there will be plenty to keep hard rock fans busy with Queens of the Stone Age, Baroness, Ghost B.C., Imagine Dragons, Foals + more to check out.
