Personally I feel that Foregone production wise is excellent. As a massive Nordström fan, I would honestly put it pretty close quality wise to the classic Colony and Clayman production. One of the main differences is simply in the amount of guitar layers and harmonies.
The other Benson albums are total crap; but everything sounds really great on Foregone. Powerful, clear and fairly organic. The main issue is of course the vocals (+ processing) on many of the tracks which could otherwise have been excellent (B minor, etc..).
If they channel Foregone Pt. 1 or the tremolo breakdown in End the Transmission throughout an entire album with the same production, we'd be in for a real treat.
