Robert Johnson

Musical styles like rock ‘n’ roll, jazz and R&B trace their roots back to the blues, which partly sprang from one man who recorded his famous "Cross Road Blues" in a San Antonio hotel room.

Blues musician Robert Johnson arrived in San Antonio in 1936 and recorded some of his most famous work, like “I Believe I’ll Dust My Broom” and “Terraplane Blues,” in room 414 of the Gunter Hotel downtown.

The modest itinerant musician would join the legends after this, but it was a fledgling time in America’s recording industry.
