Instrumentally, it's a weird one - I'd just got a couple of Cherry Audio soft-synths in a Humble Bundle, plus a free one (SEM) so after playing with a couple of them I decided to use *just* Cherry Audio* synths (I did cheat and used BFD 3 for the drums to be fair) - plus real guitar and bass of course. There's also a couple of samples I threw in at a couple of points.
* Cherry synth list:
3 instances of Eight Voice
2 instances of Polymode
Mercury-4
2 instances of DCO-106
Surrealistic MG-1 Plus
