Photographer and filmmaker Pep Bonet is known for his sensitive and in-depth documentary work in Africa, including projects on the aftermath of the war in Sierra Leone, children in Swaziland who lost their parents to AIDS, and the lives of those working in the slums of Johannesburg’s inner city. His work has appeared in National Geographic, the New Yorker, and the New York Times. But in 2008 Pep took on a completely different assignment: He was invited to capture Motörhead’s European tour, shooting the band on and off stage. That collaboration would go on until 2015—a dream for the self-confessed headbanger. We reached out to Pep to learn more about how his documentary practice informed his work with the band.
