I’m going to opine just a little about the Delta Blues. The Delta Blues masters were authentic geniuses, arguably the best example of original American genius. Every time I listen to these masters, I think about what American culture has descended to.
Pop music is more or less intended as the background music for our lives. Don’t think too much, just listen. But we can’t just listen to Delta Blues on auto-pilot. The guitar chords cut to the soul.
