I’d never heard either song before... so I had listen them both, ( Soz shhhhh you ;)) I like both but wayfaring stranger takes it. You may talk again now...lol;)
Man, this is a tough call. Like Jaimie, I had not heard of either artist nor song. I have sat and listened to both, entirely, and then one for a minute or two, paused, switched the other on, and so on down the line. I really do like them both but, my vote is Rhiannon Giddens. Her voice is more bluezy and she fluctuates it with the story she sings about. Again, it was a tough call but Rhiannon for the body and strength of her voice and sound.
