Lollapalooza 2012 Lineup: CTA, Online Ad Headliner Teases Continue (PHOTOS)

Lollapalooza organizers continued to tease the 2012 festival headliners in CTA and online advertisements this week.

Since we rounded up seven likely headliners last week, eight more ads featuring song lyrics and the "#lolla" hash tag popped up.

Since Thursday, lyrics from Sigur Ros, the Black Keys, Santigold, Kimbra and Twin Shadow have all been featured in the #lolla ads. Last week's ads include Jack White, Justice, The Weeknd, Bloc Party and more.

Consequence of Sound outlined other possible headliners based on summer tour scheduling and other clues.

Last week, the festival's early bird, $200 passes sold out in a matter of minutes when ticket sales went live. Full-price tickets to the three-day festival are still available for $230.

The full Lollapalooza 2012 festival lineup is slated to be announced Wednesday, April 11.

CORRECTION: A previous version of this story stated that "Jake White" has been teased by festival organizers as part of the Lollapalooza lineup. Instead, this was in reference to Jack White.
