"Call and Response" are hallmarks of jazz because it was incubated in the black church. Preacher calls and congregation responds…horn calls and piano responds…Langston Hughes calls and Ralph Ellison responded.

Langston Hughes wrote his famous poem, "Harlem:  A Dream Deferred"

What happens to a dream deferred?

Does it dry up like a raisin in the sun–

Or fester like a sore–

And then run?

Does it stink like rotten meat?

Or crust and sugar over–

Like a syrupy sweet? 

Maybe it just sags like a heavy load.

Or does it explode?

Langston is specifically asking about the American Dream.  Ellison’s, Invisible Man, is a response to the jazz poet’s question.
