The year 2014 gave us some unforgettable country duo and group performances. The five Grammy-nominated acts gave it their all, from the Band Perry's emotive 'Gentle on My Mind' to Little Big Town's ultra-catchy 'Day Drinking.'

Sibling trio the Band Perry struck a chord with ‘Gentle on My Mind,’ from Glen Campbell's 'I’ll Be Me' soundtrack. Their impeccable vocals combined with the poetic lyrics pay homage to a singer who has left his mark on country music, showing that the best songs defy the span of time. TBP's music video for the tune and performance of the song at the 2014 CMA Awards left fans with goosebumps on their arms and tears in their eyes.

Miranda Lambert and Carrie Underwood's sexy, sultry and oh-so-bad hit ‘Somethin’ Bad’ is 100 percent fun. The two powerhouse vocalists and their blonde hair, long legs and sassy attitudes made 'Somethin' Bad' a hit with fans, and the song was truly somethin' good in 2014. And who could forget Little Big Town's catchy song ‘Day Drinking,' especially when they got completely sopped in paint for the sake of entertainment?

Country fans rejoiced when Tim McGraw and his stunning wife Faith Hill teamed up for 'Meanwhile, Back at Mama's.' Their harmonious vocals and obvious love for one another, not to mention the mellow, simple message of the song, are hard to beat. It's country royalty at their best!

Finally, what do you get when you combine an Aussie country star and a country outlaw? A Grammy nomination. Keith Urban tapped Eric Church for ‘Raise ‘Em Up,' and it turned into a partnership worthy of a major award nod.
