American Express is rolling out a fancy new feature that will allow cardholders to tweet certain hashtags and earn "couponless savings" at national retailers. Jay-Z probably doesn't concern himself much with discount shopping, but he evidently supports the idea. Next week at the SXSW festival in Austin, Texas, the rapper will play a special Amex show set to be live-streamed on YouTube.

The Amex Sync Show Presenting Jay-Z goes down on Monday, March 12. During the show, the credit card company will unlock offers via its Twitter account, and prior to the event, fans will have a chance to tweet requests and gain access to a digital concert poster.

For folks headed to Austin next week, there are two other ways to experience Hova's gig. SXSW badge holders with Amex accounts can sync their cards with Twitter and enter to win tickets, and if that fails, the concert will be broadcast on a digital billboard downtown.

The concert will stream at 7PM CST on Monday, March 12 at, where exclusive Jay-Z footage will go live tonight (March 7) at 8PM EST.

The show will also be available for on-demand rebroadcast from March 13 to 19 on, and on Xbox LIVE.
