Andrea Keller is not only a pianist, composer, bandleader and educator, she's also the Jazz Ambassador at this year's Clarence Jazz Festival, celebrating its 30th year. She joins Andy to talk about creating a web of collaborators in her Transients series. 

Ian Thompson's book, Synths, Sax and Situationists, examines the music of the French underground that began with the Paris 'events' of May 1968. For the next decade, bands such as Daevid Allen's Gong, Red Noise and Heldon were sometimes overtly political, but always subversive. Andy talks to Ian Thompson about the times and the music.
