The 2014 CMA Music Festival is officially underway, and night two of the country music party was just as sensational as the first. This time, Miranda Lambert, Blake Shelton, and other top-notch country stars thrilled fans with their sets, and a superstar -- the one and only Carrie Underwood -- made a surprise appearance.

Country singer Travis Tritt opened Friday's (June 6) show at LP Field with 'Put Some Drive in Your Country' and even treated fans to a wailing, rocking version of 'T-R-O-U-B-L-E.'

Eric Church began his set with 'The Outsiders' and wore his trademark aviators throughout the whole thing. He also brought out Lzzy Hale of Halestorm for his song 'That's Damn Rock & Roll,' and she wasn't the only guest performer of the evening. Lambert, much to the delight of the crowd, sang 'Somethin' Bad' with Underwood, pumping up the crowd with their girl power anthem.

Other performers of the evening included Blake Shelton, who took the stage after his beautiful wife, Jason Aldean, and the Band Perry. With all of those superstars onstage, it was yet another unforgettable night of country music.
