From Addis to the Barbican and back again, this episode dives into the sound-world shaped by Mulatu Astatke — the father of Ethio jazz. With Mulatu having recently completed his farewell tour, Steve goes back to a long, previously-unreleased interview he recorded with him during the making of Hackney Colliery Band’s Collaborations: Volume One. What emerges is a portrait of a true pioneer: a composer trained in London and at Berklee, a collaborator with Duke Ellington, and the architect of a style heard across film soundtracks, samples and stages worldwide.
Expect discussions of Ethio jazz’s roots in traditional modes and tribal instruments; a journey through pentatonic and diminished scales; and Mulatu’s deep reflections on African musical heritage and collaboration. There’s even a live extract of Derashe from HCB’s Barbican show — the tune he discusses in the interview.
In this episode:
• How Mulatu fused Ethiopian pentatonic traditions with jazz harmony and improvisation.
• Why some Ethiopian tribes use diminished (whole–half) scales, and how that changes the emotional palette.
• The story of Duke Ellington’s Jazz Ambassadors tour — and how Ellington ended up performing one of Mulatu’s arrangements in Addis.
• The embilta, washint and other Ethiopian wind instruments that parallel trumpets, trombones and baritone sax.
• The link between African “bush” instruments, mbira/“African piano” traditions, and Western harmonic thinking.
• A rare 2018 interview captured at Livingston Studios during the HCB/Mulatu recording sessions.
• A live performance of Derashe from the Barbican, featuring Hackney Colliery Band and Mulatu Astatke.
