Kathryn this is for you.
The Fleet Foxes have exploded in popularity. I must say I like some covers of their tunes more than the originals. But some of the originals are pretty kick ass too.
First Aid Kit of Sweden covers "Tiger Mountain Peasant Song" - teenage Swedish sisters
Kina Grannis (and her sisters) covers "White Winter Hymnal"
The Fleet Foxes (original) "Mykonos"
