• Words and photographs by Euan Wallace in Pamplona, Colombia

As the sun rose on the cold morning of Monday 29 July in Pamplona, Colombia, a young Venezuelan man in tattered clothes woke up to the sound of the radio playing in a refugee shelter. A news bulletin was reporting Nicolás Maduro’s victory in Venezuela’s presidential election, while phones flashing with blurry footage were passed from hand to hand showing videos of violent protests circulating on social media.

The 2024 presidential elections in Venezuela have plunged the country into a new phase of political crisis since Maduro, the incumbent president, claimed victory amid widespread allegations of fraud. The leading opposition candidate, Edmundo González Urrutia, and his supporters contest the result, which has led to huge protests, including the toppling of statues of former president Hugo Chávez.

Got something you’d love to ask the Buffalo Stance singer about her four decades in music? Now is your chance

Back in 1988, when Neneh Cherry paired a gold jacket with a gold bra and a pregnant belly on Top of the Pops, the world tilted a little on its axis. But Buffalo Stance – her solo hit single from the genre-busting album Raw Like Sushi – was neither the beginning nor the end of Cherry’s illustrious and vanguard-chasing artistic career.

Born in Sweden, the daughter of textile artist Monika “Moki” Karlsson and Sierra Leonean musician Ahmadu Jah, she grew up thoroughly bohemian; US jazz musician Don Cherry was both stepparent and father figure. The family divided their time between rural Sweden and bustling, down-at-heel 1970s New York, where she had a ringside seat while Cherry Sr combined free jazz with world music. Talking Heads were her neighbours.
