British funk pioneers Cymande, whose rhythmic grooves have been sampled by hip-hop legends De La Soul, The Fugees and Queen Latifah, make a long-awaited Glastonbury debut after years in the shadows. Then it's over to reggae royalty as Black Uhuru step up with a set spanning more than five decades. Expect a politically charged, roots-driven performance that will resonate with longtime fans and new ones alike.
