This has to be the easiest one to decide on so far.
Okay, so they're a duo, and they're awesome, and I have to thank Taylor so much for the recommendation. I can't even pick one of their songs to showcase. I love their sound. It's like a mix of country and folk, but it's really beautiful. Their voices are both great, and they compliment one another. I mean, it may remind you a bit of The Civil Wars, but Elenowen has a much more country sound than The Civil Wars does.
Their music is deep and rich. The melodies flow well. And I just gahhh!!!
Here just listen to them sometime.
(I'm going to write a review of their album soon-ish too. That will be better than this mess.)
