Sleigh Bells, Two Door Cinema Club also to take the stage when the show airs live on March 16 at midnight ET.

On Tuesday (March 1), Wiz Khalifa, Sleigh Bells and Two Door Cinema Club were announced as performers at the 2011 mtvU Woodie Awards, set to air live on MTV, MTV2 and mtvU from the South by Southwest Music Festival in Austin, Texas, on Wednesday, March 16, at midnight (ET/PT).

Wiz, Sleigh Bells and Two Door Cinema Club are also up for awards at the seventh-annual show — Wiz is in the running for Woodie of the Year, given to the year's best artist, and Sleigh Bells and TDCC are facing off against each other in the Breaking Woodie category, given to the year's best breakout act. But you don't have to be an actual nominee to perform, as evidenced by the fourth act confirmed to take the stage: insane L.A. rap collective Odd Future, who will most certainly keep the censors on their toes.

The Woodies also announced the first wave of presenters for the 2011 show: Matt and Kim, Lupe Fiasco, Dev, Chiddy Bang, emerging Eminem protégé Skylar Grey and Liz Lee, the star of MTV's "My Life as Liz," will all be in attendance to hand out the hardware.

Additional performers and presenters will be announced in the coming days. As in previous years, Woodie winners will be determined by fan voting, but if you want to have your voice heard, you better act fast: Voting in most Woodie categories closes Tuesday, though votes will continue to be counted in the Breaking Woodie category right up until the show itself.

The 2011 mtvU Woodie Awards will air live on MTV, MTV2 and mtvU from the South by Southwest Music Festival in Austin, Texas, on Wednesday, March 16, at midnight ET/PT.
