Don't be fooled -- this isn't a folksy cover. What Avec Sons have done here is pretty dramatically different from the original, but oh so awesome!
A relatively unknown group out of London, Avec Sans have a distinctly synth-pop sound, instantly comparable to Mr. Little Jeans. Their Facebook page gives very little detail as to what their deal is, save for that there are two members: Alice Fox and Jack St. James.
Either way, it's a unique take on the song, one I personally enjoy quite a bit.
