John O'Connor has been playing music with friends all his life; his main instrument is the bass. He always saw that music had the power to make people happy, but also to make them think, so he was drawn to music with a purpose. Through a nonprofit organization he helped found, Concerts Unite Us, he is putting on concerts for equal justice. He says we don't use the power of music to address social issues as much as we should. He says music was prevalent in the civil rights, antiwar, and other movements. He believes music can help those who are sick, but also those affected by modern propaganda.
