I love everything I've heard by First Aid Kit (their performance of "Emmylou" in front of Emmylou Harris at the Polar Music Prize award ceremony is probably my favorite live video on YouTube). The writing here is not as strong as on some of their songs, so I'm giving it a 90.
I didn't know Maggie Rogers. Her voice is strong and powerful, and she doesn't try to sound like the multitude of bland pop music female vocalists we're cursed with nowadays (she does remind me a bit of Ingrid Michaelson, whom I also like very much). Again, I think the singing is stronger than the writing. These two artists are very different, but I'm awarding them the same score: 90.
