From: Photo Flash: Inside the 2012 Grammy Nominations Concert!

GRAMMY Sunday reigns as Music's Biggest Night, but a very close second is 'The GRAMMY Nominations Concert Live!!' - an event that blends one-of-a-kind, GRAMMY-worthy performances with the official announcement of the songs, albums and artists that are in the running for music's greatest golden honor. For the fourth consecutive year, the nominations special was broadcast live on CBS, but a houseful of lucky attendees got to witness the unique spectacle in person on Nov. 30 at the Nokia Theatre L.A. Live in Los Angeles.
