When photographer Sascha Kraus asked the Tunisian rap artist Hamada Ben Amor (aka El Général) why he wrote the song Rais Lebled, the answer was simple: “I took the risk because no one else did.” The song was directed at then-President Zine El Abidine Ben Ali; the rapper spoke of police brutality, poverty, violence, and free speech. After it was released on Facebook, El Général was arrested. Rais Lebled became the battlecry of the revolution.

Kraus’s book FORTHRIGHT – Stronger than a weapon is an ode to all the hip hop and rap artists who have risked their safety to say what’s on their mind, often in verse. The photographer devoted six years of his life to traveling and recording stories at home in Germany, in the United States, in Africa, Europe, Asia. The book is designed like an old fashioned album booklet, with lyrics, pictures, and in-depth interviews between Kraus and his many subjects.

In total, 43 artists are included. They come from opposite ends of the globe, but FORTHRIGHT is a book about connections rather than divisions. Darryl McDaniels of RUN-D.M.C out of Hollis, Queens, identifies with Emmanuel Jal, an activist and former child soldier from South Sudan. Every one of Kraus’s subjects is inextricably linked to the others, despite political or geographical boundaries. Whether they set out with the intention to change the world or simply to write a song, these musicians took action against suffering. Many had a hand in helping to reshape political tides, elections, laws, and human rights.

Despite the hurdles his subjects faced—indeed, some risked their lives by speaking out—Kraus finds reason for hope. He remembers the time he traveled to the remote villages of Senegal with rapper and women’s rights activist Sister Fa. “What really touched me,” he says, “are the children’s bright eyes. They are so happy that someone comes to give a concert, and it is pure joy to see the smiling faces.”

Some of these artists, like Emmanuel Jal, author of the book War Child: A Child Soldier’s Story, didn’t get to have happy childhoods, but now, they’re striving for a peaceful future for other boys and girls. In music, they found not only a safe place but also a reason to hope

In conversation with Kraus, Burmese artist Zayar Thaw said, looking back on his time in prison, “We were not allowed to have pen and paper, so I wrote on the wall.” FORTHRIGHT is a tribute to all who dared write on the wall.
