Here are a couple that really stood out to me, but of course one could spend a lifetime going back a few more years to see who these other folks' influences were, and theirs, and theirs ...
https://www.youtube.com/watch?v=H3FNLnFg6Ck - Goree Carter, Rock a While 1949!
: Guitar riffs at time = 0:00, 0:35, 0:57 (!!), and mini solo at 1:30.
: And heck, piano throughout sounds just like a young Jerry Lee Lewis might have, esp. at 2:02 (but it wasn't him!).
And "here's the riff upon which Chuck Berry based his career*"! Louis Jordan and his Tympani Five, "Ain't That Just Like a Woman" - 1946!! : https://www.youtube.com/watch?v=YEqiWTb-UWA
: First notes of the song, and the solo at 2:25
* David Tomar http://www.thebestschools.org/magazine/ ... -and-roll/ - amazing link, a labor of love!
I got to see him live once at the New Orleans Jazz Fest, I actually don't remember much about the show beyond thinking for it's entirety, "I can't believe I'm standing here watching Chuck Berry".
Thank you for everything, Chuck Berry.
(And thank you youtube!).
