In November 2011, UNESCO officially designated 30 April as International Jazz Day in order to highlight jazz and its diplomatic role of uniting people in all corners of the globe.

International Jazz Day [opens in new window] is chaired and led by Irina Bokova, UNESCO Director General, and legendary jazz pianist and composer Herbie Hancock.

Radio Cardiff marked the 5th annual International Jazz Day with a whole day of special shows from 7am to midnight, starting with a 3 hour extended edition of A Slice of Jazz. Catch up with the shows below.
