Richard Pryor was a groundbreaking comedian that pierced through the shell of 1970s mainstream America... I remember as a little kid my parents receiving a copy of "Is It Something I Said?" for a Christmas present and I wanted to hear it played. My parents, of course, with older generations present, squirmed uncomfortably and made some excuse about the record player... later I played it myself and learned about a new culture. It was revolutionary humor, it was cultural storytelling and it kicked open the door for others to follow him. It is often remarked that what was most remarkable about Pryor was his simultaneous rage and vulnerability... soemthing I could understand.
