Welcome to Chicago!

The Windy City's Grant Park is home to Perry Farrell's annual Lolla extravaganza from August 6-8. This year's fest features many notable sets, including a reunion of Seattle grunge pioneers Soundgarden and New York City guitar rockers the Strokes. Of course, a little pop star named Lady Gaga will be there, too, just to keep things interesting.

SPIN's editors studied the line-up and picked 25 acts you don't want to miss. And we added some songs and videos to this story, so even if you're not heading to Chicago, you can still enjoy the music. -- Written by Steve Kandell and Peter Gaston
