This weekend, over 140 acts will descend on Chicago's Grant Park for this year's three-day Lollapalooza festival. And while there's no doubt we'll be rocking out to headlining sets by Black Sabbath, Jack White and Red Hot Chili Peppers, they're far from the only awesome artists hitting the stage. Do yourself a favor and show up early enough to catch these must-see acts that are a little lower on the bill, from Bassnectar to The Tallest Man on Earth.
