In syrupy slow pursuit of a strong 2023 debut, Yungwebster's somnolent sequel is bolstered by pitch-perfect production from Space Afrika and Nathan Melja, who vaporise the rapper's auto-tuned post-Future drawl with euphoric orchestral drones, brittle micro-trap beats and weightless pads.

Over a decade ago at this point, Future released 'Codeine Crazy', the decelerated finale of 'Monster', one of his best-loved mixtapes. The track neatly summarised themes the Atlanta rapper had been circling for years at that point, layering his slurred, lean-dizzy rhymes over producer TM88's rubbery, melancholy synths. "Take all my problems and drink out the bottle," he moaned robotically, using the track's minor key bounce to represent the crushing delirium that followed fame and its tasting menu of intoxicants. It's still Future's high water mark creatively, and its traces can be observed in a full spectrum of contemporary sounds, from 6LACK's downtrodden, self-aware R&B to Lil Uzi Vert's feverish trap. But it's Yungwebster who's taken the haze to its logical conclusion, reimagining the Magic City-sculpted bumps as hypnagogic Actavis- 'n Xanax-hued ambient music. You could argue it was bound to happen - the more you sip, the slower it gets - and plays as a cracked mirror to cloud rap's long-smoked hybrid of Southern psychedelia and post-OutKast eccentricity.

Webster's opiated POV is clearer than ever before on 'II'. Just peep the cracks in his voice on the Space Afrika-produced opener 'Skyfall' as he coughs and splutters over watery samples, booming subs and SA's patented collage of soundtrack-ready strings and sirens. Presented at regular speed and in chipmunked form, it sets the pace for an album that, like its predecessor, constantly fucks with the timeline, pitching the whole master into doubletime or slowing it down to a crawl to present a curved, inebriated narrative rather than a straight line. Even without the tempo switches, Webster singles out beats that accent his warbled rhymes that sound as if they'll fall apart at any moment. French DJ and producer Nathan Melja backs 'Disheveled' with Black Ark-styled oscillations and airlock'd echoes, filtering the bassline until it almost disappears entirely; with room to breathe, Webster's able to take the lead - you might not be able to pick out the words, not entirely at least, but you get the message.

In fact it's Webster's voice that's the revelation on 'II' - with a coherent mix from producer tnotsobad, the nuances and fluttering tonalities emerge more vividly than they have before. It makes the flip between the regular speed and fast on 'Txts Red on iMessage' a textural decision, the different pace shifting the warbled cadences so Webster's voice becomes far more important than the additional elements. And on the album's Space Afrika-produced eight-minute centerpiece 'Crochet / I Swear', Webster's mumbled bio-mechanical whines create a much-needed foil for the decelerated boom-clack and suspended save room ambience. We get to encounter a personality here, not just an aesthetic, so as the album moves into its twilit fourth side, the beatless, voice-led somniferousness of 'YA SA' and ululating 'Phone' come off like a descent into tranquillised sedation. Rap has rarely sounded so chimeric.
