Grammys 2013: Follow the nominations live on Twitter An emotional Adele reacts while accepting her sixth Grammy of the night during last year's Grammy Awards. Robert Gauthier / Los Angeles Times / December 5, 2012 By Todd Martens and Scott Sandell December 5, 2012, 4:49 p.m. The Grammy nominations are set to be unveiled in an hourlong show from Nashville starting at 10 p.m. PT/ET Wednesday and airing on CBS. Though Adele was the big headline last time around, this year the picture is a bit cloudier, with no obvious front-runner. Adele's "21," the bestselling album of 2011, has once again led the way this year, according to Nielsen SoundScan figures. And the biggest album of 2012 that was actually released in 2012 is not eligible for Grammy consideration: Taylor Swift's "Red" missed the Sept. 30 cutoff date for the current Grammy nominations with an Oct. 22 release and will have to wait unti the 2014 show. Meanwhile, the other usual Grammy suspects - Kanye West, Lady Gaga, the Foo Fighters, etc. - have albums in the mix. So the stage is certainly set for surprises. Will newcomers like Frank Ocean, the New York group fun. or Lumineers get the nod? Find out who does and who doesn't here, with live updates on Pop & Hiss and from Times staff on Twitter below.
