Some kind of weird whistle-like sounds mixed in with the beat here. :D And a steady thump all the way, keeps the energy high; keeps you going...
Bass seems a little loud, like it maybe distorts the kick a little, but I like the grimy sound otherwise. Not as sure about the whistles, they're a little over the place, atmospheric but also chaotic, in an unplanned, structureless kind of way, sometimes they're great, sometimes they just feel a little off IMO. Hesitant. Out of tune. May be the style you're going for but still might be worth polishing that layer a bit more too. Seems there's an order to chaos too; to get it really syncing with a beat in a good way.
Dope stuff overall, keep it up!
