Their second work after PTXmas to not feature any original material, the album marks a departure from the group's typical sound, which mostly consists of either modern pop songs or Christmas music, choosing instead to focus on standarts of rock, blues, country, and older pop music.
"Jolene", featuring the original artist, Dolly Parton, earned her and Pentatonix a Grammy Award for "Best Country Duo/Group Performance".
