"Without Elvis, there is no Gene Vincent or (Silver)Beatles"
Without black blues musicians there is no Elvis, no rock n roll, no jazz, no swing.....
Chuck Berry made the bridge ... without him no Elvis, no Beatles, etc
Not meaning to argue and Son House is my personal blues favorite but blues were not the only component of rock and roll.
There is most definitely Appalachin Folk, traditional Country and Western, Gospel and Minstrel and Blues all rolled together.
Delta blues really seriously influenced 60s harder edge rock bands....they took it and ran well with it.
It's a shame so few of the early giants....Johnson, House or Patton ever had any decent recordings done. All of Johnson's stuff was done on junk recording equipment. I don't think Patton (who started as a minstrel in my opinion) ever had access to decent technology either.
Son House did courtesy if Alan Lomax Sr whom we all owe bigtime or we would have almost nothing on the early greats.
The latter giants like Muddy and Wolf or Hopkins had some well recorded stuff.
I have an old copy of a Son House dead letter recording originally made on a piece of thick metal ...I forget what they call it. It's from the early 20s and at an evening church social in Indianola Miss....you can hear the old steam train coming by while it's recorded.
anyhow...sorry for the rant...Sat morning meandering...sometimes I think folks like Jimmie Rodgers, Hank Williams, the Carter Family, Bob Wills and others from the mixed aforementioned genres are forgotten about as major influences on early rock and roll as well....the blues masters not withstanding.
I plead ignorance about Jazz....I know some the names, that's all
