Just four years into Aphex Twin’s post-comeback career, Richard D. James is making some of the best music of his life. Maybe that sounds like hyperbole or provocation. He’s got a formidable track record, after all: Between 1991 and 2001, he turned electronic music on its ear more than once, giving the world a number of classics in the process. But since 2014’s Syro, James’ music has been marked by the kind of freedom you don’t often get from an artist who’s been making records for 27 years.

Every album he’s put out since he returned from a 13-year hiatus as Aphex Twin has sounded unmistakably like his own inimitable self while at the same time breaking new ground. The wide-ranging Syro, his reintroduction to the world, was a kind of stylistic clearing-house—that much was apparent from the wide-ranging BPMs he listed in brackets in the track titles. The tropes were familiar but the sounds, flickering like holograms, were a touch more vivid than before. With Computer Controlled Acoustic Instruments pt2 EP, he ditched the synths and let a robot combo loose on acoustic drums and prepared piano; what could have been abstruse instead radiated a quiet magnetism. Orphaned Deejay Selek (2006-2008) rescued some rave bangers from the archive, while the Cheetah EP, in 2016, was a lark, basically: seven low-key doses of low-slung funk banged out on an obscure, infamously difficult-to-program synth from the 1990s. Nerd manna, sure, but also irresistibly groovy and surprisingly unencumbered—just straight-up fun, really.

With the Collapse EP, he doubles down on those pleasure principles, even as he returns to some of the knottiest programming he’s tackled since the mid-’90s and songs like “Flim.” All five tracks are descendants of the manic style once called “drill ‘n’ bass”: The drums skip and stutter, bouncing like ball bearings in an earthquake. It’s a safe bet that no two bars are alike, though it would take a forensic analyst to map the minuscule variations of his splintered rimshots and blood-spatter drum drip. His rhythms have never been more dynamic: He’s taken the slow-fast lurch of classic drum ‘n’ bass and fractured it into ever tinier shards, with kicks and snares setting off percussive chain reactions and elastic triplet patterns being pulled taut into zippers of pure buzz.

As usual, he applies wistful synth melodies to smooth over those jagged edges. The melodies are, by and large, the least surprising things here, though they are also among the most satisfying. Until the drums kick in, “pthex” starts out sounding like an outtake from Selected Ambient Works Volume II, its elongated steel-pan synths suggesting intonation systems not quite of this earth, while detuned harp plucks add extra kinks to his funhouse-mirror surfaces. In “MT1 t29r2” and “T69 collapse,” the tuning feels even screwier, casting an eerie glow over the rhythmic wreckage.

What feels new to this release is way the music moves on a wider scale. James’ arrangements thrash spasmodically like beasts unwilling to succumb to the tranquilizer dart. There’s a real sense of violence underpinning these tracks: “T69 collapse” breaks down, halfway through, into a heaving mess of drum fills and haywire-robot pummeling—wild, senseless aggression, bewildering in its kinetic energy. “abundance10edit[2R8’s, FZ20m & a 909]” is less brutalizing but it still lurches like a machine run amok. You’d think that would be a bad thing, but no—those white-knuckled moments are an essential part of the record’s fucked-up beauty, just like all those queasy, quicksilver tones. It’s not quite wrong but definitely not right, either. The thrill lies in James’ ability to juggle precision and chaos—it’s part laser-guidance system, part demolition derby—and somehow come out of it relatively unscathed.

That said, “1st 44,” by far the best thing here, is also the simplest. It’s a straight-up drum track, practically a DJ tool stripped back to jackhammering sequences of claps and snares and some of the biggest, boomiest bass drums ever heard on an Aphex Twin record. It’s a virtuosic display of programming and sound design alike, the kind of tune that could plaster a shit-eating grin on any raver’s face—outdoor, basement, or armchair. Then, for good measure, he goes and slaps the time-stretched bark of a reggae deejay over the top of it, as though it already weren’t hype enough. There have been times in James’ career when his knowing smirk threatened to eclipse the music. But here he’s obviously having a genuine blast, and his joy is infectious.
