Last night's ‘X Factor‘ boot camp round featured at least two country artists. Tim Cifers and Kingston impressed judges during their group performance of Rascal Flatts‘ ‘I Won’t Let Go.’

Cifers, from Willow Springs, N.C., began the song before each contestant entered the stage one at a time. Simon Cowell announced, “He’s (Cifers) a contender that guy."

And Kingston — formerly known as the Carter Twins — shined, as did 34-year-old Thomas Wells, a chicken plant worker from Oklahoma.
