Something that generally catches my attention when it comes to Alistair's works, is the impressive manner in which he uses samples.
On the drop of "Z3n", melodies from a shimmering trumpet ornament the stereo field. And what makes the passage even more memorable are the catchy vocal chops that have undergone some heavy pitch shifting.
The atmospheric tones within the track are also accentuated during the verses as Alistair strips "Z3n" down to drums, synths, and soothing guitar strums. If you have a study playlist, this would slip in perfectly.
