In recent years, festivals have tried to shake up the usually staid process of revealing their lineups (little more than a press release and an embargo) with "Wheel of Fortune"-style puzzles and marathon MySpace unveils that involved [article id="1631616"]flying light bulbs[/article]. But for the 10th anniversary of Austin City Limits, the folks behind the fest have attempted to spice things up by going in the opposite direction: They're unveiling their lineup via a delightfully lo-fi series of scratch-off cards.

As part of the "Lineup Lottery," ACL has been distributing cards through various Austin-area venues, and fans can learn who's on the bill simply by scratching. So far, they've revealed names like presumed headliners Arcade Fire, plus My Morning Jacket, Cee Lo and Chromeo. But thanks to an even lower-fi source, we may now know the identity of the other two headliners: [artist id="1230523"]Kanye West[/artist] and Stevie Wonder.

In the June issue of Spin magazine (a scan of which you can see here), both West and Wonder are listed along with Arcade Fire, and, over the weekend, Austin360.com music journo Michael Corcoran wrote on his Twitter account that the rumors "are on the mark." Reps for either artist could not be reached for comment by press time.

The full Austin City Limits lineup is reportedly set to be unveiled Tuesday. All told, some 150 bands will perform at the fest, which is set for September 16-18 in Austin's Zilker Park. Three-day passes for the 10th ACL have already sold out, with one-day tickets set to go on sale Tuesday through the fest's official site.
