Richard Cambridge’s poetry, novels, art, and theatre productions address controversial themes on the American political landscape. His theatre-troupe Singing with the Enemy (co-founded with Cuban-American singer/songwriter Patiño Vazquez) produced Embargo! portraying the fifty-year U.S. blockade of the nation of Cuba, and (with former Black Liberation Army member and political prisoner Kazi Touré) Presente! a dramatic mural about the plight of political prisoners and prisoners of war in the U.S.
In 2004 he received the City of Cambridge Peace and Justice award for the contribution of his art and activism.
