First published 25 years ago, Eno’s diary now reads like a time capsule of more innocent Britpop times, before Blair and Iraq, Brexit and Trump. But beyond its limited hindsight value, this sprawling chronicle of the avant-pop professor’s busy bohemian schedule is peppered with erudite mini-essays on creativity, technology, terrorism, politics and more. David Bowie, Bono, Lou Reed, Laurie Anderson, Elvis Costello and Paul McCartney all have supporting roles.
