Who is Hideho Heights from Harlem Gallery and what is their importance?

Hideho Heights is the poet laureate of Harlem. He comes across as loud, silly and foolish. He loves his jazz, his Satchmo (or Louis Armstrong), and even likens jazz to marijuana for the black man. The black people of Harlem worship and love him and his poetry. They gather at the Zulu Club to hear Hideho recite his poetry, to which he receives thunderous applause. Shockingly, out of the mouth of ridiculous Hideho, comes the wise words of a preacher.
