The Barr Brothers are taking things in a different direction with this song but still incorporating the harp. It makes for an interesting and unexpected listen.
The description for this song is one worth knowing about. The soundcloud description reads:
"This song, Half-Crazy, could be described as the tenacious offspring of the North African desert music of Mali/Morocco and the sweat and electricity of the Chicago and Mississippi Delta blues. That music is like a stem-cell, really open to going in many directions. On this track, we wired the harp through a dirty little amplifier. I played my early 40's Oahu lap-steel. Andrew uses a loping high-hat feel, and the electric bass pushes the whole thing. The lyrics got a nudge from our friend Nathan Moore--we're all half-crazy, half clear as a bell."
