It's going to be a tough fight for Vocal Group of the Year at the upcoming 2013 CMA Awards. The nominees in that category this year include some of the top groups in country music today.

Eli Young Band couldn't be any hotter, with last year's breakthrough, 'Even if It Breaks Your Heart.' Lady Antebellum have done it again with their most recent album, 'Golden,' for which they are embarking on a massive worldwide tour. Little Big Town moved their career to the next level in the last year, with a string of hits that show off their vocal blend perfectly.

The Band Perry are hotter than ever with their new album, 'Pioneer,' while the Zac Brown Band continue to impress as one of the best vocal and instrumental groups in country music today.
