The thing is he built the songs slowly with Guy, starting from a main idea with just guitar chords, then they start thinking about the arrangements, usually doing demos with bass and drums lines programmed by MK, trying different guitars and amps very slowly...
What it takes very little time is when the band is in the studio to play the songs live all in the room, as everything is pretty planned and althought there is a room for improvisation, they all know the guidelines before they even start so with a bunch of proffesional musicians from Nashville, that is going to be fast, but the preparation work with MK and Guy alone, that takes a lot of time as they are not in a hurry and have a lot of different brands of Tea to try as well.
And how then does it differ from over-production and overly long post-production Mark was complaining basically from the beginning of his solo career? Instead of long post-production, let's have a long pre-production then but rush everything else. Is this how it works now?
It's quite remarkable how Mark steps in the same water so many times. Dire Straits ended with a long exhausting tour, 9 people on stage, overly produced albums or whatever. Mark's solo career has its sunset (judging by 2 cover pictures in a row) with 11 (!) people on stage, a long exhausting tour, and overly pre-produced albums.
We all love Mark and it's a fan forum, I know, just want to remind people to lower their expectations and never take anything for face value.
