1953
→Horns and voices, doo-wop harmonies in stairwells, R&B spilling across the color line, and the audience that would demand rock and roll forming in real time.
1954
→R&B crosses the color line, a teenager in Memphis fuses blues and country on tape, and the electric guitar gets a body that fits.
