Extinctions

Poet Daljit Nagra revisits the BBC's radio poetry archive with 'The Echo Chamber - Extinctions'.

Paul Farley listens to old and new poetry of extinction 100 years after the death of Martha, the last ever passenger pigeon.

With poems from Fleur Adcock, Sean O'Brien, WS Merwin and David Harsent and the sounds of X-ray audio, the samizdat music of the Soviet Union that used black-market plates of skulls and ribcages to capture the beginnings of rock n' roll.

Producer: Tim Dee

First broadcast on BBC Radio 4 in 2014.
