The details of this year's Lollapalooza festival are beginning to trickle in. Aside from early reports of headliners Mumford & Sons, Phoenix, Vampire Weekend and the Killers, many more bands and artists are now confirmed to perform. Artists recently added to the bill include The Postal Service and The National.

Lollapalooza is set for August 2-4 in Chicago. Tickets have yet to go on sale, however discounted Early Bird Passes will go on sale at 10 a.m. Central on Tuesday, March 26. In addition, festival officials announced that "souvenir" passes for $75 will be available via a secret sale some time this week.

As of now, that's all we know. Anxious festival goers are stuck on the edge of their seats waiting for any further details of the luminous secret sale. Based on past Lollapalooza festivals, the best and only way to get the inside dirt is to follow the festival's social media accounts, like Facebook and Twitter, and to sign up for e-mail alerts.

Last year, 750 secret sale tickets became available for purchase on March 20 and sold out in less than a minute. The regular passes are sold for $235 and will go on sale after secret and Early Bird tickets are all spoken for.

So if you're dying to go to Lollapalooza but are a bit strapped for cash, be sure to stay on top of your game and snag one of the coveted secret sale passes. Nothing is sweeter than paying less than everyone else.

The official 2013 lineup will be announced next month, but check out a brief list of confirmed artists while you wait via Consequence of Sound.
