Archie Shepp — American Musician born on May 24, 1937,

Archie Shepp is an American jazz saxophonist. Shepp is best known for his passionately Afrocentric music of the late 1960s, which focused on highlighting the injustices faced by African Americans, as well as for his work with the New York Contemporary Five, Horace Parlan, and his collaborations with his "New Thing" contemporaries, most notably Cecil Taylor and John Coltrane...

And when I met Cecil Taylor it was a complete transformation of musical identities. All the tenets that I had grown up with were thrown out the window.
In America, for a brief time, people who followed Coltrane were studied and considered important, but it didn't last long. The result is that the kind of music I played in the '60's is completely dismissed in this country as a wrong turn, a suicidal effort.
So, I was just a young guy, maybe with an idea, and Cecil Taylor, himself a rebel, would take a chance on a guy like me. It turned out to be a very symbiotic partnership. I learned a lot from him.
In rap music, even though the element of poetry is very strong, so is the element of the drum, the implication of the dance. Without the beat, its commercial value would certainly be more tenuous.
Negro music and culture are intrinsically improvisational, existential. Nothing is sacred. After a decade, a musical idea, no matter how innovative, is threatened.
