‘Surrender’ opens with Bono on a gurney in an up-market American medical facility in 2016, eye-balling the physician who’s about to crack open his chest. ‘I have an eccentric heart’, the singer writes wryly, one he spends the guts of a fine, meaty autobiography trying to define. Busy with detail and as rich with candid testimony as it is with relentless name-dropping, ‘Surrender’ is an unpacking of that heart from inside a travelling salesman’s suitcase.
