Soul Scream - 黒い月の夜器楽 // Night of the Black Moon (Instrumental) 

Re-produced by me in Audacity via looping. One of the chillest and best beats I've ever heard. Listen to the entirety of The "Deep" by Soul Scream, even if you don't speak Japanese. The beats, musicality and harmony are still very much enjoyable.
