The Grammy Nominations Concert Live! airs Wednesday, November 30 at 10 pm Eastern on CBS. The event marks the fourth time the Recording Academy has produced a live special to announce the slate of nominees. Performers in the one-hour special, hosted by LL Cool J, include Lady Gaga, Rihanna, Sugarland, Nicki Minaj and Katy Perry.
