 While discussing the 2006 remix of My Life in the Bush of Ghosts at a dinner party , Eno suggested finishing some songs that he had written but that did not have lyrics . Byrne visited Eno 's studio to listen to the demos and the two decided to collaborate to finish writing the songs . They continued working on the tracks in New York City and London , with regular e @-@ mail correspondence to finish the composition . Multi @-@ instrumentalist and previous Eno collaborator Leo Abrahams performed guitar , percussion instruments , and piano in his London home studio and played guitar with Byrne on one occasion . Abrahams would continue working on the tracks in his home studio through May 2008 , with all collaborations being carried on via e @-@ mail .
