How to Play 'Demons' by Imagine Dragons

The song is from the band's 2012 album 'Night Visions'.  We are in 4/4 time at 90 Beats Per Minute and you will be using a capo on the 3rd fret to match the sound of the original recording.

Imagine Dragons' songs are great to learn because they often have very straightforward chord progressions which can be elaborated upon depending on your level.  With 'Demons' the song at it's simplest has one progression (see below):

You can use this progression throughout the song strumming quarter notes or whatever strum you are most comfortable with.

I found live performances of the band playing the song and they play at a lower pitch, playing the chords with open strings.  The guitars are also tuned down a semitone (so, from low to high you will have Eb Ab Db Gb Bb Eb) presumably to save their voices a little.
