“A people without the knowledge of their past history, origin and culture is like a tree without roots,” said civil rights leader Marcus Mosiah Garvey, a thought that could just as easily apply to the history (or lack thereof) of music.

For Tyrone Jefferson and Toni Tupponce, A Sign of the Times’ legacy is to share these oft-forgotten stories of black history through music, dance and spoken word.
