CHICAGO (CBS) — Music fans wasted no time Tuesday morning snapping up early-bird specials for this year’s Lollapalooza music festival.

Early bird three-day passes for Lolla went on sale at 10 a.m. for $200 and if you blinked you missed them. Within minutes they were sold out.

But if you are willing to pay a little bit more, you can still get three-day passes for $235.

The event this year runs August 2-4 in Grant Park. The lineup won’t be officially announced until another couple of weeks but in addition to Mumford and Sons, speculation has included Vampire Weekend, The Killers and Phoenix as other potential headliners.
