Twenty years ago today, the Perry Farrell-spawned Lollapalooza festival — which, in retrospect, joins Nevermind as perhaps the best historical encapsulation of ‘the year punk broke’ — made its debut in the sun-baked Arizona desert with performances by Nine Inch Nails, Living Colour, Siouxsie and the Banshees and Jane’s Addiction.

Our partners at GroopEase are giving away two pairs of three-day passes along with $500 cash to see The Cars, Big Audio Dynamite, Foo Fighters and more at the massive Lollapalooza festival in Chicago’s Grant Park on Aug. 5-7.

While an official announcement is still forthcoming, the reunited Big Audio Dynamite is plotting what looks to be a two-week club tour across the U.S. this August to coincide with its slots at Lollapalooza in Chicago and the Outside Lands Festival in San Francisco.

The organizers of Lollapalooza tonight unveiled the lineup for this year’s 20th anniversary festival, and while there are no throwbacks to that inaugural 1991 fest, there are a couple acts on the bill older than the event itself: Big Audio Dynamite and The Cars.

After Perry Farrell debuted a brand-new Jane’s Addiction track on South American radio during the run-up to the band’s headlining appearance at the inaugural Lollapalooza Chile, the track spread across the web — so the group decided to give away the finished version for free.

With Jane’s Addiction in South America for this weekend’s inaugural Lollapalooza Chile, frontman Perry Farrell took to the airwaves to debut ‘End to the Lies,’ a track off the band’s forthcoming album ‘The Great Escape Artist.’
