The BBC’s 1960s jazz programme returns for a one-off special celebrating the recent resurgence of the genre by a community of young Londoners, largely educated through grassroots organisations rather than conservatoire traditions. Presented by drummer Moses Boyd and DJ Jamz Supernova, the Jazz 625 studio hosts performances from saxophonist Nubya Garcia, groups Ezra Collective and Sons of Kemet, and singer Poppy Ajudha.
