Daisuke Nagata - Karous remixed soundtrack Defect in my Head
I've never actually played the full Karous soundtrack on here before, but I have played some of Nagata's other EPs with remixes of some Karous tracks. The original soundtrack is very dark, oppressive-sounding drum and bass, and this set of remixes very much leans into the darkest and moodiest parts of the original.
The full album isn't streaming anywhere, but I can at least embed the official trailer with previews of several tracks.
