William S Burroughs recordings made with Brion Gysin (credited with the invention of the cut up technique) have been released by the British Library. The 23 audio recordings are largely previously unreleased, sourced from the library's audio archive. The release centres around a 42 minute recording of Burroughs in Liverpool from 1982, where he reads excerpts of The Place Of Dead Roads, Nova Express and the story Twilight's Last Gleamings.
The CD also includes 1960s recordings of Gysin performing his permutated poems, plus home recordings made in Paris by Burroughs and Gysin in 1970. More details here, and download extracts here and here.
