American composer and musician Carla Bley has been one of the most distinctive voices in jazz through the second half of the 20th Century and now into the 21st.
For 40 years, her music has moved through different styles and different ensembles - from duos to big band, from free jazz in the 60s to her unique blend of improvisation and composition.
She talks to John Fordham, who is joined during the series by her musical friends and colleagues John Cumming, Andy Sheppard, Steve Swallow and Lew Soloff.
The focus moves away from her early work in the 60s and 70s to her chamber jazz duos with double bass player Steve Swallow and the formation of her Big Band.
Soloists Andy Sheppard (saxophone) and Lew Soloff (trumpet) also talk about their work with Carla Bley.
He talks to Carla about her smaller scale compositions for Trio and Quartet as well as her commitment to touring with the Carla Bley Big Band.
With contributions from soloists Andy Sheppard, Steve Swallow and Lew Soloff.
