As with the other significant genres, blues has many variations: jump blues, country blues, folk blues, Chicago blues. I have delved as far as I care to in the appropriated form (and I know that all the great genres and offshoots are appropriated)

I think some of the language in death cafe is a little dense for the blues, which comes right out and says it. Or, at least, provides a colourful metaphor that gives us the full nudge and wink.

The humour is earthy not esoteric. The drama is in real life depiction of what the songwriter experiences. Stories are about the protagonist in situations. There’s a lot of first person: I’m a back door man, I’m a hoochie coochie man, I’m the seventh son

You know and I know that that is the same man. One Willie Dixon. In my opinion the greatest blues songwriter.

The blues has such diversity that these observations can’t cover all of the genre all the time. But they’re a good field guide.
