Following a sweet-as-sweet-tea introduction by the iconic Martina McBride, newcomer trio the Band Perry carried their hits 'If I Die Young' and 'You Lie' onto the CMA Music Festival stage -- and onto our television screens on 'Country's Night to Rock.'

The sibling set stood in a row as they rocked their first melodic hit in a laid-back performance, armed with an accordion, a bass and an acoustic guitar, and Kimberly Perry's big vocals. As they gained some cred with the crowd, the sister singer enticed the fans to sing along, and many waved their arms as instructed.

"Sing it with us Nashville!" Perry shouted, and hundreds of thousands of country fans sang along in unison. The singalong quickly turned to screams, however, when the Mississippi Perrys drifted from their 2010 single into their 2011 hit, 'You Lie.' From there, it was no holds barred.

'If I Die Young,' from the Band Perry's self-titled album, has gone two times platinum since its introduction -- and their gold status follow-up single isn't far behind. Just recently, the trio announced a headlining tour as well as mega-dates with headliners Keith Urban and Reba McEntire, set to kick off August 15.
