Daves Highway are a sibling trio from Brandon, Miss., and although they're not 'country' per se, they're Southern as all get-out, and their Christmas covers are perfect for the holiday season! Delaney, Zachary, and Erika Daves are self-taught musicians, which is amazing in itself, but borderline hard to believe once you witness their talent.

The trio put the 'Christ' back in Christmas with their version of 'O Come All Ye Faithful,' with Zachary telling the camera he loves this holiday season and "to celebrate Jesus and how he was born." As Zachary plays the acoustic guitar, he and his sisters harmonize ... and it's beautiful! After watching the faithful rendition, check out the family's 'Blue Christmas' cover below.
