This is among the most musically opulent Chillhop tracks I've heard in a very long time! It feels like there is a lot going on when it comes to each arrangement however "In-Depth" is honestly comprised of a minimalist stature.
Instead of opting for a wide range of synths and instruments on a track, the producers on here have used only a handful in a skillful manner. It was the elegant piano runs that appear towards the closing moments which blew me away especially since they had a jazzy touch to them. I can't neglect to mention the beefy bass line exuding life into the low end - that was also among the notable moments in the track.
