I think that duets are great, especially when they contain powerful lyrics. This song is filled with emotion, about whether it can be dealt with, or whether you have to run away.
Nemesea itself has been around for a while I imagine, I don’t know how I came across them, but the vocals are really smooth, I love the song itself. Of Monsters and Men had a really good duet too, but it got played to death on the radio (what the radio is best known for.
This is poetically strong, and easily one of my favorite songs, primarily for the amount of meaning behind the words.
