Kanye West And Jay-Z, Black Keys Lead 2012 Woodie Noms

The mtvU Woodie Awards are heading back to South by Southwest, and this year, they're going to be bigger than ever.

That's because on Wednesday, mtvU announced that, in addition to the awards themselves, the Woodies will channel the SXSW spirit and become a daylong festival. It begins March 15 at 1 p.m. CT with a host of live performances — open to all SXSW badge holders (though, if you're not going to be down in Austin, you can watch the fest unfold live on Woodies.mtvU.com) — and culminates with the 2012 Woodie Awards.

The best moments from the awards will air on MTV and mtvU on March 18 at 8 p.m. ET, though music lovers can stay up-to-date on all Woodie-related mania — interviews, performances and SXSW updates — beginning on March 11, when Woodie Awards Week kicks off on MTV, mtvU and MTV.com.

Woodie performers will be announced in the coming weeks. Fans can vote for their favorite nominated artists beginning Wednesday at Woodies.mtvU.com. Kanye West and Jay-Z, the Black Keys, Skrillex, Mac Miller, Frank Ocean, J. Cole and others lead the field, vying for the coveted big hunks of wood in categories that include Woodie of the Year (given to the artist who left their mark on music in 2011) and the Performing Woodie (given to the year's best touring musician). And this year, the Woodies have unveiled a brand-new category to honor electronic dance music: the EDM Effect Woodie.

Voting in Woodies categories closes March 9, except for Breaking Woodie, which is open all the way until March 15.
