I've been listening to "Shifting City" recently - I'd forgotten what a great album it is - very unique. "Through My Sleeping" and "An Ocean We Can Breathe" are fantastic songs.
I've also discovered "The Golden Section" - I've had it on CD for about a year but never given it a good listen until now. Some great tracks on here like "The Hidden man", Twilight's Last Gleaming" and "Ghosts On Water". Some of the bonus tracks/b-sides are really great too!
One of the many things I enjoy about John's music is the variation - every album has it's own sound, style and mood.
