Alright. I thought I would comment on this song, because the more I listen to it, the more my brain is telling me to analyze it.

With “Snake Eyes” it can be argued that it displays the transition Mumford & Sons sounds have gone through over the course of their three albums. The first section of the song correlates with the sounds off of Sigh No More: there is soft strumming, drumming, and singing.
The next section relates with Babel as the sounds begin to pick up much like the songs of “I Will Wait” and “Babel.”
The last section of the song can be seen as an introduction to the sounds of Wilder Mind as it brings in the heavier, electric sound alongside powerful drumming and vocals.

Take a listen for yourself and let me know what you think:
