i/o is 12 tracks of grace, gravity and great beauty that provide welcome confirmation of not only Peter’s ongoing ability to write stop-you-in-your-tracks songs but also of that thrilling voice, still perfectly, delightfully intact. Throughout the album the intelligent and thoughtful – often thought-provoking – songs tackle life and the universe. Our connection to the world around us – ‘I’m just a part of everything’ Peter sings on title track i/o – is a recurring motif, but so too the passing of time, mortality and grief, alongside such themes as injustice, surveillance and the roots of terrorism. But this is not a solemn record. While reflective, the mood is never despondent; i/o is musically adventurous, often joyous and ultimately full of hope, topped off as it is, by the rousingly optimistic closing song, Live and Let Live.

Renowned for being a boundary-pushing artist, i/o is not simply a collection of a dozen songs. All 12 tracks are subject to two stereo mixes: the Bright-Side Mix, handled by Mark ‘Spike’ Stent, and the Dark-Side Mix, as reshaped by Tchad Blake. “We have two of the greatest mixers in the world in Tchad and Spike and they definitely bring different characters to the songs. Tchad is very much a sculptor building a journey with sound and drama, Spike loves sound and assembling these pictures, so he’s more of a painter.” Both versions are included on the double-CD package, and are also available separately as double vinyl albums. And that’s not all. A third version – the In-Side Mix, in Dolby Atmos, comes courtesy of Hans-Martin Buff “doing a wonderful job generating these much more three-dimensional mixes” and is included in three-disc set, including Blu-ray.
