The simplicity is particularly easy to understand. The fact that this little number is conjured out of an acoustic guitar and two vocalists really does make it obvious ... though, the way on which the pair work together does give you the impression that more might be being used, when, it actually isn't.
It's sophistication comes more-so within the choruses. The female vocals, in particular, have the vibrato that carry it through, and the power they both convey really does make it much more of a scene, rather than just a song with some words - we adore how they've pulled this off.
We wonder how long it'll be until this sort of music makes its way round to the UK again, as it is just a matter of time until it's massive. The US already adores the likes of The Civil Wars ... and also She & Him, so we wonder if round here that vibe will soon hit once more and, when it does, the name we can put forward as a country is The Honey Ants.
