the drums sound like they were recorded with minimal mic techniques, probably using 4 mics at a guess, sounds like ribbon mics, it's certainly a dark sound and mellow, could even be recorded to tape, there isn't much high end there. At a guess the acoustic guitar sounds like an sm57, it doesn't have the normal high end sheen. My guess is that the album was recorded to tape and mixed through a console, possibly mastered to tape as well, it sounds very analog, but I could be wrong, they might have just mixed it to sound like tape and it's digital.
