Lollapalooza lineup: The Chain Gang of 1974 and Tennis due at this year's fest in August

​Lollapalooza turns twenty years old this year. Can you believe it? We can't. Doesn't seem like it was two decades ago when Perry Farrell introduced America to his roving festival in 1991. The inaugural version, which made a stop at Fiddler's Green, featured Farrell's band Jane Addiction, along with Nine Inch Nails (not on the Colorado date, though), Butthole Surfers, Ice T, Rollins Band and Siouxsie and the Banshees, among others.

The tour became a little more diverse and compelling each year until 2005, when it stopped being a tour and set up shop in Chicago at Grant Park and became a destination festival. Lollapalooza has since hosted an array of acts from Lady Gaga and Kanye West to Radiohead and Depeche Mode to the Killers and MGMT to Arcade Fire and Mumford and Sons.

This year's edition of Lollapalooza, slated to take place August 5-7, is being headlined by Eminem, the Foo Fighters, Coldplay and Muse, and has a pretty healthy undercard that includes Deadmau5, Deftones, Bright Eyes, the Cars, Lykke Li, Local Natives, Crystal Castles, Sleigh Bells and Best Coast, along with a few locals -- the Chain Gang of 1974 and Tennis, among a host of others. Deeply discounted advance tickets have already sold out, but three-day passes are still available for $215, if you're so inclined.
