There will be more band sessions for sure, scheduled date for finishing is March 2018, 5 months yet.
I think they record the same material over and over on each band session, the only difference is different microphones...
Actually I doubt very much that happen in the band sessions. I'd say they do two or three takes as maximum, and that would be too much.
Is before the band sessions, when MK and Guy are alone, where they spend days and weeks just trying mics and amps.
Band sessions are expensive, each musicians gets paid for hours of work, that's why when they come, everything is ready to record quickly.
