Sundy Best was formed by two friends since elementary school, Nick Jamerson and Kris Bentley, from Prestonsburg in Eastern Kentucky. Both were athletes in college, with Jamerson playing football while at University of Pikeville where he studied history, and Bentley played basketball at Centre College in Danville where he studied English. They formed a duo after college, and moved to Lexington, Kentucky in August 2010. Jamerson performed as the lead vocalist and played the guitar, with Bentley on the cajón drum. Their name referred to the way they pronounce "Sunday best", their best clothing worn in church where they began playing music together on Sundays during their senior year in high school.

“For those of you who may not know, Sundy Best is a duo out of Prestonsburg, Kentucky composed of Nicholas Jamerson and Kris Lee Bentley. Between then and 2018, Sundy Best wrote, recorded, and toured in a prolific manner, releasing three more albums, a live album, and several singles following that debut record, for a total of nearly 100 songs in just over four years. As a result, they quickly gained a massive following and rose to the top of the regional country scene, experiencing quite a bit of national success as well. Known for songs like “Painted Blue,” “Hindman,” and “I Wanna Go Home,” the duo found themselves in a position of Appalachian country music royalty and one of America’s national non-mainstream up and comers.”
