Hugh Masekela and Seth Lakeman onstage at Charlton Park

Mary Ann Kennedy and Lopa Kothari are joined by Lucy Duran and Andrew McGregor for the first of a weekend of broadcasts from the globe's leading festival of world music, live from the festival site in Charlton Park in Wiltshire. The mighty Hugh Masekela headlines on the Open Air stage, and from the Siam Tent we hear Carlou D from Senegal and the innovative Finnish accordion of Kimmo Pohjonen. From Radio 3's own stage in the shady Arboretum, English folk star Seth Lakeman performs live, and making their UK debut performances are Cape Verde's Michel Montrond, and a new young voice from Azerbaijan, Nazaket Teymurova. Plus interviews and truck sessions, starting off more than eight hours of live broadcasting from WOMAD.
