Odd time signatures, jazz harmony, unusual scales - there's a lots of complicated musical ideas. There isn't a dull moment when you're tinkering with so much, there's always an unexpected turn around the corner or at the next track. The F# major to A dominant 7 was pretty spicy in Subaquatic Saunter (Action).
The soundtrack starts of oozing with 90's vibes with some modern polish. By the time I reached the end, Mechacanthine Foreboding and Epilogue (Within the Soul) stick out a bit to me; the samples are a bit too good and the performances are a little too realistic when compared to the more proudly digital start of the soundtrack.
Nevertheless, it's a very eclectic combination of sounds and musical ideas. Even if it doesn't always sound cohesive it's never boring. Kudos.
