BOB Marley's reggae star son will top the bill at Womad music festival this year.

Five-time Grammy Award-winning reggae superstar Ziggy Marley is one of the biggest names in the Malmesbury festival line-up, which has been announced today.

Also on the bill is UK techno group Orbital, guitarist Anna Calvi, Mali singer Salif Keita, funk legends Cymande, Afro-punk band Tshegue and Caribbean rock trio Delegres.

The festival will feature a series of talks and debates, as well as space-themed workshops and events aimed at children.

Womad founder Peter Gabriel said: “Womad our world music festival, was established with the specific intent of featuring all the richness and magic of our cultural differences. Meanwhile, across the globe we're watching cynical politicians growing powerful on a diet of fear and hate. The world is more divided than ever and there’s never been a better reason for people to bring all the barriers down, to relax and connect through music, art and dance. Every year at Womad it is our differences, our diversity, that become the reason we want to be together.”

The festival runs from Thursday, July 25 to Sunday, July 28, at Charlton Park, near Malmesbury. Four day tickets are £225 for adults and free for children under-13. SN16 residents can buy discounted tickets.
