Tom Holland is joined by Dr Lucy Robinson from the University of Sussex to consider jazz in the trenches, woad and the women behind the Notting Hill Carnival.

Helen Castor meets Dr Michael Hammond, Associate Professor at the University of Southampton, to hear about Blues in the Trenches. Dr Hammond argues that 'the blues' as a musical tradition was brought to the trenches of the Great War by African-American soldiers from all parts of the US and they shared different performance styles and traditions - creating cross-pollinations that foreshadow the country blues recordings of the 1920s and 30s by Charley Patton, Furry Lewis, Bukka White, Geechie Wiley, Ma Rainey, Elvey Thomas, Blind Willie Johnson and notable others.

Closer to home, on the banks of the River Thames, Iszi Lawrence traces the origins of today's craze for tattoos and body art back to the Celts, when she learns to make woad.

On the eve of the Notting Hill Carnival, comic Ava Vidal nominates the activist, feminist, socialist and founder of the Carnival Claudia Jones for the Making History plinth.
