Festival director Chris Smith said: “While artists around the world are still subject to travel restrictions we are delighted – following the ‘Womad Roadmap’ – to announce a line-up that fully illuminates the rich cultural diversity of the UK’s artistic community.
“We will announce more UK-based artists in the coming weeks and hopefully be able to add international artists to the line-up after May17 if international travel allows.
“Inevitably there will be some changes to the festival this year and we will implement the measures required for the festival to take place safely and for the wider community to feel totally comfortable so that we can all come together to celebrate the world and enjoy all the things that enrich our lives and are essential to the human spirit.”
