These were classified as blues but I think you can call them R&B too. They feature three of the best guitarists of the era playing loud.
“Canton Mississippi Breakdown” (1954) has Elmore James and Ike Turner on guitar.
“Boogie Uproar” (1953) is by Clarence “Gatemouth” Brown. “Space Guitar” (1954) is by Johnny “Guitar” Watson.
The sax solos look back to the 1940s but the guitar solos are headed into the future.
