A bit late to this one (partly as I tend to cringe when I think there's a blues coming, and tend to cringe twice if the song has blues in the title!).
However, there's nothing too formulaic about this one - it has a taste of some of those old (Delta?) R&B tunes with slightly crazy guitar patterns which always seem to work... (Could it be the alternate tuning?)
Clever lyrical twist as well - refining lyrics is the only way I know, so maybe I can also learn something from this (save me from the lyric-overthinking blues?)
Cool and different - and effective.
