I seem to have fallen off the acoustic-only bandwagon on this one. I always seem to fall down at least one production rabbit hole every February.
Vocals sampled from "Ashes" by Ghost, which is the first place my mind went to when I saw this week's challenge.
The instruments are a heavily processed octave mandolin, plus some softsynths, so I guess I still followed my "no guitar" rule?
You know this one.
