Jay-Z will play SXSW 2012 in Austin, TX.

Yep, you read that right. After a few days of rumors (which included the not-yet-vetted Eminem), it’s been confirmed that Jay-Z will be performing at SXSW 2012. Details are still rolling in, but we know the show goes down at SXSW on Monday, March 12th at 8pm EST, and will be livestreamed on the AmEx YouTube channel if you can’t make it. Or if you’re one of the 50 bajillion people there invetiably won’t be room for on the guestlist.

The show is sponsored by the new American Express Sync Card, which allows you to connect your AmEx card to your Twitter account and tweet out promotional hashtags to have those deals auto-loaded onto your card. AmEx will be demonstrating the technology by raffling off event entry to SXSW badgeholders who sync their AmEx cards and tweet about the #JayZSyncShow. Still no word on exactly how this will work, but we’ll clarify with more details as they come to light. (It might behoove you to bug @AmexSync about it on Twitter.)
