American composer Caroline Shaw’s latest album, a collaboration with Sō Percussion, is called Rectangles and Circumstance. It’s a collection of ten songs run through with words by Emily Dickinson, Emily Bronte, William Blake and Christina Rossetti, as well as Caroline herself. She joins Andy from her home in the US to talk about her collaborators and her co-poets.

When Irish singer songwriter David Keenan came onto the scene he was described as “the sound of Tim Buckley and Brendan Behan arguing over a few jars, while Kavanagh deals Dylan a suspicious hand of cards, and Anthony Cronin and Jack Kerouac furiously try to scribble it all down” – so no pressure there. He talks about wearing those comparisons, writing songs about Ireland, and the story behind his guitar as well as performing new music live.
