On November 23, 1936, two men sat down in front of a microphone and began to play.

These two men couldn't have been more different. One was a cello prodigy who had performed before the Queen of Spain.

The other played guitar in the juke joints of the Mississippi Delta.

This is the sound of one of the world's greatest classical cellist,

and probably the most legendary blues guitarist of all time, jamming together.

Of course, it didn't really happen.

Not like that anyway.

Pablo Casals and Robert Johnson were an ocean apart.

But on the same day in 1936, they both made recordings that would change music history.

Music made recordings that would change music history. I first met Robert in 1936, same year he recorded.

He wasn't famous at the time.

My name is Honeyboy Edwards.

I'm a guitar playing and I play the blues.

Back in them days, on a Saturday night, everybody would go up at the roadhouse,

have music, have barbecue,

That old boy should play a guitar.
