Artists and music fans from around the world have been rediscovering the 1970s sound of Zambia known as Zamrock in recent years, and now one of the country's biggest stars is embracing it, hoping to give it a fresh twist.

When devising her third studio album, Sampa the Great looked to the niche, brief musical movement that ignited her birth country more than 50 years ago.

"We were looking for a sound and a voice that was so post-colonial. And Zamrock was that sound - that sound of new freedom, that sound of boldness," the Zambian-born, Botswanan-raised rapper - who has performed at the likes of Glastonbury, Coachella and the Sydney Opera House - told the BBC.

Zamrock - with its heady blend of psychedelic rock and traditional Zambian sounds - rears its head on Can't Hold Us, the first single to be released from Sampa's upcoming album.

Fuzz guitars thrust the song forwards, as 32-year-old Sampa, full name Sampa Tembo, defiantly raps: "They don't have the guts to match my prowess."
