And here's another fascinating Kieran Press-Reynolds piece: How Hyperspeed Squeals & Alien Whispers Became Rap's Final Frontier. It's a deep-dive into the online realm of bedroom rappers who boldly go way out there, - beyond Playboi Carti's baby-voice, beyond even his fetus-voice - into outermost zones of "rap-sing insanity" that sound more like "experimental ASMR or the national anthems of an alien civilization" than MC-ing as hitherto known. Artists like 645AR, lungskull, meat computer, Axxturel, sellasouls, islurwhenitalk, Jewelxxet et al are leaving behind words and even decipherable emotions for pure texture-play, breath-braiding and vocal-goo extrusion.
Here is Kieran's YouTube playlist for the artists and tracks mentioned in the piece.
