A consummate innovator, Gysin altered the cut-up technique to produce what he called permutation poems in which a single phrase was repeated several times with the words rearranged in a different order with each reiteration. An example of this is "I don't dig work, man/Man, work I don't dig." Many of these permutations were derived using a random sequence generator in an early computer program written by Ian Sommerville. Commissioned by the BBC in 1960 to produce material for broadcast, Gysin's results included "Pistol Poem", which was created by recording a gun firing at different distances and then splicing the sounds. That year, the piece was subsequently used as a theme for the Paris performance of Le Domaine Poetique, a showcase for experimental works by people like Gysin, François Dufrêne, Bernard Heidsieck, and Henri Chopin.
