ZZ Top - My Head's In Mississippi

It's hard not to like Zztop.  They're originals, have been doing it for a long time, and represent a direct line to a blues sound that gave birth to and has always underlain rock.  All of this ameliorates the Southern, back country patriarchal, misogynistic urges that their raw sound is also steeped in.
This song is one of their later hits and one of my favorites, although they do tend to repeat themselves in songwriting, playing, production, soloing, etc.
