The multi-talented musicians were held back in their home country where even certain instruments were off limits – but they’re ready to take centre stage at Worthy Farm

Walking into an industrial estate in Peckham, I can hear impassioned cries coming out of a rehearsal space located here. Soaring vocals are punctuated by the gentle strum of a thumb piano along with bells that are strapped to the shaking ankles of Pendo and Leah Zawose, who make up the Zawose Queens. It’s their first time playing this music outside Tanzania – and if that wasn’t enough of a culture shock, some of their first-ever UK gigs will be a trio of sets at Glastonbury this weekend.

“We don’t really have any idea about Glastonbury or what it will be like,” says Pendo, via Aziza Ongala who is the band’s manager and acting as a translator. “But I’m told it’s a big deal. I’m not sure we’re going to be able to grasp how big of an experience it is until we actually do it but we’re very excited.”
